Singapore contracted Oracle for isolated defence cloud & AI (Mar 2025) — first such deal in the region. Malaysia launched ILMU LLM (Aug 2025). Singapore's SEA-LION pre-trains on 13 regional languages.

Chinese military drones have demonstrated transponder spoofing over the SCS, transmitting false aircraft identities — a likely test of electronic deception relevant to grey-zone and kinetic scenarios.

Reuters (Feb 2026): Chinese military drone (callsign YILO4200) made 23+ flights over SCS since Aug 2025 transmitting false transponder IDs. PLA AI enhances OODA loop speed in cyber and space per ASPI (Apr 2026).

Adopted at the ADMM Retreat in Penang, Malaysia on 26 February 2025, all 10 ASEAN defence ministers committed to accountable and responsible AI use, explicitly stating that accountability cannot be transferred to machines. Flags risks of miscalculation, overdependence, and a lower conflict threshold. Encourages ADMM-Plus expert groups to incorporate AI. Statement is voluntary with no verification mechanism.

Effective 1 March 2026, Vietnam's AI Law is the first legally binding national AI legislation in Southeast Asia, leapfrogging the voluntary approaches of Singapore and Malaysia. Covers cybersecurity, intellectual property, and defence AI applications with phased enforcement through 2030. Sets a binding standard that other ASEAN states are now benchmarking against.

ASEAN Member States published the Expanded Guide on AI Governance and Ethics covering generative AI, intended to support greater policy alignment across the bloc. The guide is non-binding and operates alongside the ASEAN Responsible AI Roadmap and the Working Group on AI Governance (WG-AI) established in 2025. Significant variation in national implementation persists.

With the Philippines as 2026 ASEAN Chair, this is the targeted conclusion year for the long-negotiated COC. Key issues — geographic scope, legal bindingness, and enforcement mechanisms — remain unresolved after two decades. ASEAN claimant states favour binding provisions; China resists constraints on operational freedom. Analysts are broadly skeptical a substantive binding text will be finalised under Manila's chairmanship.

Released by Singapore's Cyber Security Agency on 17 June 2026, the addendum addresses security risks specific to agentic AI systems — AI that can autonomously plan and execute multi-step tasks. Directly relevant to autonomous C2 and autonomous weapons adjacent systems being developed by SAF and DSTA. Positions Singapore as the region's leading standard-setter for defence AI guardrails.

Issued at the ADMM Retreat in Penang, Malaysia (26 Feb 2025). The first statement on military AI at the ASEAN Defence Ministers' Meeting, affirming that accountability cannot be transferred to machines and encouraging ADMM-Plus expert working groups to incorporate AI into their work and discussions.

Under Malaysia's 2025 ASEAN chairmanship, the 58th ASEAN Ministerial Meeting communiqué welcomed the Feb 2025 ADMM AI statement and expressed concern about the 'negative consequences and impact of autonomous weapon systems on global security and regional and international stability.' A diplomatic milestone for norm-setting.

Announced by Minister Josephine Teo at the World Economic Forum (Feb 2026). Requires organisations to maintain human accountability for AI agents, implement technical controls, and ensure operational transparency. Directly relevant to autonomous defense systems.

Formally addresses malicious ICT activity by state and non-state actors, including criminal and terrorist groups, and records the growing impact of AI-enabled attacks on critical infrastructure. Represents the cybersecurity-track complement to the ADMM defense AI statement.

The first binding national AI law in Southeast Asia, effective March 2026, passed alongside updated cybersecurity and IP legislation. Covers phased implementation 2026–2030. Vietnam's AI Law is considered by analysts the regional benchmark against which ASEAN's fragmented soft-law approach is being measured.

Under its 2026 ASEAN chairmanship, the Philippines committed to presenting a regional AI regulatory framework based on draft domestic legislation. Paired with Manila's push for a South China Sea Code of Conduct text, this represents the most ambitious dual-track governance initiative in ASEAN's history.

Issued at Penang (Feb 2025); encouraged ADMM-Plus expert groups to incorporate AI cooperation. Voluntary, leaves operational definitions and verification open. AMM 58th Joint Communiqué (2025, under Malaysia's chair) expressed concern over 'negative consequences of autonomous weapon systems on global security.' Operational deployment is outpacing these institutional guardrails.

Passed by Vietnam's National Assembly in late 2025; phased rollout 2026–2030. Enacted alongside updated IP and cybersecurity laws with AI-specific incident provisions. Enforcement capacity still being built at Ministry of Science and Technology. Sets regional benchmark that Indonesia and Thailand are watching closely.

Announced December 2025, led by the US; 24 signatories including Singapore and the Philippines. Directly competes with China's WAICO (est. July 2026, 37 members, including Indonesia, Brunei, Malaysia, Vietnam, Laos, Cambodia, Myanmar). ASEAN must navigate this US-China AI rivalry without fracturing bloc unity.

Adopted at ADGMIN-6 (Hanoi, Jan 2026) under Philippines' 2026 chairmanship theme 'From Connectivity to Connected Intelligence.' Covers AI cooperation, trusted data flows, and digital infrastructure. ASEAN AI Safety Network (est. 2025, secretariat: Kuala Lumpur) leads regional capacity building and regulatory preparedness.

ASEAN Guide on AI Governance and Ethics published 2024; Expanded edition and Responsible AI Roadmap published 2025. Voluntary, risk-based approach modeled on OECD AI Principles and UNESCO Ethics Recommendation. Administered by WG-AI. Indonesia and Thailand using this as primary governance reference pending domestic binding law.

REAIM 2024 Blueprint for Action (Seoul) widely supported; Singapore co-hosted. ADMM Cybersecurity and Information Centre of Excellence (ACICE), launched 2023 and led by Singapore, operates the Malware Information Sharing Platform giving ASEAN states exclusive access to tactical cybersecurity threat intelligence. ACICE leads CERT-to-CERT capacity building and cyber exercises in 2026.

Issued at the ADMM Retreat in Penang on 26 February 2025. Affirmed that accountability cannot be transferred to machines, encouraged ADMM-Plus Expert Working Groups to incorporate AI into exercises, and called for coordination in leveraging AI while proactively addressing risks. Voluntary with no operational definitions or verification mechanisms — widely described as a floor, not a ceiling.

Malaysia, as 2025 ASEAN Chair, brought military AI into the foreign ministers' joint text. The 58th AMM communiqué welcomed the February ADMM AI statement and expressed formal concern about 'negative consequences and impact of autonomous weapon systems on global security and regional and international stability.' Marks normative escalation from technical to political-level concern.

In January 2025, ASEAN adopted the Expanded ASEAN Guide on AI Governance and Ethics focused on generative AI. In March 2025, ASEAN adopted the ASEAN Responsible AI Roadmap. Both instruments are non-binding but provide the framework within which national AI laws (Vietnam, Thailand draft, Philippines proposed framework) are being shaped. Military and dual-use AI remain inadequately addressed.

Under the theme 'Navigating Our Future, Together,' the Philippines has elevated AI governance and the SCS Code of Conduct as twin 2026 priorities. Former House Speaker Romualdez signaled the Philippines would present an AI regulatory framework to ASEAN in 2026 based on draft Philippine legislation. The dual-track approach links economic AI governance directly to security applications for the first time at chairmanship level.

Building on the February 2025 Joint Statement, ASEAN defence establishments were directed to incorporate AI elements into ADMM-Plus Expert Working Group table-top (TTX) and field training (FTX) exercises. Cross-pillar policy exchanges between ADMM officials and the ASEAN Working Group on AI Governance (WG-AI) were initiated. The 19th ADMM in November 2025 advanced this mandate. Verification and definitions remain open gaps.

Adopted at the ADMM Retreat in Penang, Malaysia (Feb 26, 2025). Affirmed that accountability for AI-enabled systems cannot be transferred to machines and encouraged ADMM-Plus expert groups to incorporate AI coordination. The 58th AMM joint communiqué (2025, under Malaysian chairmanship) built on this, welcoming the statement and expressing concern about 'the negative consequences and impact of autonomous weapon systems on global security and regional and international stability.' Voluntary and leaves operational definitions and verification open.

Enacted December 2025, phased implementation 2026–2030. Vietnam's Law 134/2025 is the region's most comprehensive binding AI legal framework, covering AI across cybersecurity, IP, and defense-adjacent domains. Enforcement capacity gap acknowledged: Vietnam's Ministry of Science and Technology is still building technical assessment capabilities. Passed alongside updated cybersecurity and IP law.

Published by ASEAN Member States to provide guidance on general-purpose AI governance and ethics, intended to support greater policy alignment across ASEAN. Part of a broader soft-law ecosystem that remains voluntary and fragmented. Defense-specific application requires extrapolation; no binding enforcement. Runs alongside the Philippines' push to table a binding AI regulatory framework at ASEAN under its 2026 chairmanship.

Under its 2026 ASEAN chairmanship theme 'Navigating Our Future, Together,' the Philippines tabled an AI regulatory framework based on draft Philippine Congressional legislation. If adopted, it would open partnership with Singapore, expand digital-governance influence, and create the region's first binding multilateral AI rules. Experts warn the economic and technological divide may deepen as member states adopt AI at different paces, complicating consensus.

Released 17 June 2026 by Singapore's Cyber Security Agency as an addendum to its 2024 AI security guidance. Provides lifecycle controls for system owners to identify where autonomous agentic AI workflows could be exploited — directly applicable to defense AI systems.

The 13th Malaysia Plan positions AI as a key pillar of national development with an aspiration to rank Malaysia among the world's leading AI nations by 2030. Defense-AI governance remains voluntary; formal AI law timeline is not yet set. AI governance focus is shifting toward accountability and trust frameworks.

Under its 2026 ASEAN chairmanship, the Philippines committed to presenting a regional AI regulatory framework based on draft domestic legislation. Paired with Manila's push for a South China Sea Code of Conduct text by July 2026, this represents the most ambitious dual-track governance initiative in the region.

Under Malaysia's 2025 ASEAN chairmanship, autonomous weapons concern was inserted into the AMM joint communiqué, welcoming the February ADMM AI statement and flagging the 'negative consequences' of LAWS on international stability.

The 2nd REAIM Summit (Seoul, 2024) produced a Blueprint for Action building on the 2023 Call to Action. Singapore co-hosted and cited REAIM as the global platform underpinning its responsible-AI defence posture.

Launched under the ADMM Cybersecurity and Information Centre of Excellence (ACICE) in 2023 with Singapore as a founding driver. Provides member states exclusive access to tactical cyber and disinformation threat data.

NAIS 2.0 frames Singapore's defence AI as part of a broader civil-military confluence balancing innovation, organisational agility, and responsible governance—serving as a template other ASEAN states reference.

Published Sep 2025 and building on the AMM communiqué, the proposal urges ASEAN to translate its joint statement into a practical annex defining human control, auditability, and verification for AI involved in targeting and escalation management.

Issued February 2025 at the ASEAN Defence Ministers' Meeting. Voluntary and non-binding, it leaves operational definitions and verification mechanisms open but signals bloc-level political will. The 58th AMM communiqué subsequently expressed concern over 'negative consequences of autonomous weapon systems on global stability.'

Built on OECD AI Principles and UNESCO ethics recommendations, the Guide's seven principles (transparency, fairness, security, reliability, privacy, accountability, human-centricity) are being embedded into national laws at different speeds. By end-2025, all 10 AMS had at least initiated an AI governance strategy, with Brunei completing its Guide in 2025.

Anchored in draft Philippine legislation, the proposal aims to mitigate cross-border AI risks including data misuse and disinformation. If adopted, it would constitute ASEAN's first region-wide enforceable AI instrument and open a Singapore-Philippines co-leadership dynamic in digital governance.

Published September 2025, the proposal argues ASEAN must move beyond voluntary statements to verifiable norms before major-power capability races make restraint impossible. It does not seek a full ban but a time-bound agreement on specific high-risk LAWS categories.

Launched 2023 with Singapore as a co-founder. ACICE provides ASEAN member states exclusive access to tactical and technical cybersecurity threat intelligence. Its Malware Information Sharing Platform is the most concrete deliverable of ASEAN's collective cyber governance architecture.

Published under Singapore's stewardship; described by Singapore's SMS for Defence as a 'critical foundation for trust'. Does not yet have a defence-specific annex on targeting, release decisions, or escalation management.

Widely supported by member states including ASEAN nations. Focuses on responsible AI in military contexts but lacks enforcement mechanisms. Singapore uses REAIM participation to reinforce its 'responsible AI' branding regionally.

Welcomed the February ADMM AI statement and expressed explicit concern about 'negative consequences and impact of autonomous weapon systems on global security and regional and international stability'. Analysts at Lowy Institute call for this to be converted into binding practical steps.

Launched by Singapore in 2023. Functions as the operational hub for coordinating ASEAN military cyber-AI activities under the ADMM framework. Increasingly relevant as AI-enabled cyber operations proliferate across the region.

Approved 2025–2026; covers naval, air, and coastal AI-enabled systems. Includes BrahMos AI-guided cruise missiles. Creates pressure on neighbours to accelerate own programmes. Pax Silica US AI hub in Central Luzon adds dual-use AI infrastructure dimension.

Issued February 2025 at the ASEAN Defence Ministers' Meeting; encourages ADMM-Plus expert groups to incorporate AI and coordinate efforts. Voluntary, lacks operational definitions or verification mechanisms. Malaysia's AMM chairmanship embedded concern over autonomous weapons consequences into the 58th AMM Joint Communiqué.

Enacted December 2025, phased implementation from March 2026 over four years. Introduces risk-based AI system classification, a National AI Development Fund, and regulatory sandboxes. Paired with updated cybersecurity and IP statutes. Enforcement mechanisms to be formalized during implementation phases.

Launched in 2023 with Singapore's support. Serves as the institutional hub for ASEAN member states to coordinate on cybersecurity and information domain challenges, increasingly overlapping with AI-enabled threats. Provides the bureaucratic infrastructure to implement ADMM AI commitments.

The Philippines is developing domestic AI capacity through the Center for AI Research (CAIR) and Education Center for AI Research (E-CAIR), underpinned by a strategy prioritizing talent, ethics, and innovation. As 2026 ASEAN Chair, Manila is promoting AI adoption among MSMEs and shaping regional AI agenda.

Published 2025, expanding the 2024 ASEAN AI Guide with a GenAI focus. Prompted establishment of ASEAN Working Group on AI Governance (WG-AI). Six member states have national AI strategies; Cambodia, Lao PDR, Myanmar still drafting.

Adopted 6 November 2025. Notes 96-state informal CCW consultation attendance in May 2025. Falls short of mandating further formal consultations. US, Russia, China resist binding constraints; governance gap widens as technology accelerates.

Established under Singapore Budget 2026. Council provides strategic direction for Singapore's AI agenda across civilian and defence domains. Paired with Champions of AI programme, AI skills initiatives, and deep-tech venture funding.

ASEAN SG participated in the 2026 World Artificial Intelligence Conference and High-Level Meeting on Global AI Governance, articulating ASEAN's collective perspective on responsible AI. Reflects growing bloc-level AI diplomatic ambition beyond bilateral arrangements.

Passed by Vietnam's National Assembly in late 2025, effective March 2026 in phased rollout over four years. Enacted alongside updated IP and cybersecurity laws with AI-specific incident provisions. Enforcement capacity still being built at Ministry of Science and Technology. Sets regional benchmark that Indonesia and Thailand are watching.

ASEAN Guide on AI Governance and Ethics published 2024; ASEAN Responsible AI Roadmap published 2025. Voluntary, risk-based approach modelled on OECD AI Principles and UNESCO Ethics Recommendation. Singapore's AI Verify tool is the world's first AI governance testing framework and feeds into regional standards. Malaysia, Brunei frameworks remain voluntary; Indonesia awaiting Presidential Regulation.

Lowy Institute analysis (Sep 2025) proposes a narrow, time-bound ASEAN agreement mandating human veto for lethal action, 3–5 year moratorium on highest-risk LAWS deployments, test-notification transparency measures, and an incidents hotline for South China Sea. Modelled on Southeast Asia Nuclear Weapon-Free Zone. Not yet a formal ASEAN agenda item but referenced in Malaysia's 2025 AMM communiqué.

Japan's OSA budget jumped to ¥18.1B (≈S$147.6M) for FY2026 — sharply up from ¥8B in FY2025. Targeting ~12 recipient countries with emphasis on surveillance radars and UAVs. Philippines, Malaysia, Indonesia are repeat recipients; Thailand joins FY2025; Vietnam, Cambodia, Laos identified as priority candidates. PM Takaichi framed OSA as essential to Free and Open Indo-Pacific at Oct 2025 ASEAN Summit.

Malaysia's 2025 ASEAN chairmanship brought military AI and autonomous weapons into the AMM text, expressing concern about 'negative consequences and impact of autonomous weapon systems on global security and regional stability'. Lowy Institute analysts call for a narrow time-bound moratorium modelled on SEANWFZ.

Passed by Vietnam's National Assembly in late 2025 and phased into effect from March 2026. Uses a sectoral body model to classify high-risk AI activities. Enforcement capacity at Ministry of Science & Technology is still being built. Sets a legislative precedent that Indonesia and Thailand are watching.

Two complementary instruments: the ASEAN Guide on AI Governance and Ethics and the ASEAN Responsible AI Roadmap (2025). Singapore's Minister Balakrishnan at the UNSC described them as 'critical foundations for trust and responsible adoption of AI by ASEAN Member States.' Most governance frameworks across SEA remain voluntary.

Singapore established four guiding principles governing the development, testing, and deployment of AI-enabled military systems. Singapore also co-hosted the 2nd REAIM Summit in Seoul (2024), contributed to the REAIM Blueprint for Action, and chaired the UN OEWG on ICT security 2021–2025.

RSIS policy paper ahead of the 19th ADMM (Nov 2025) proposed a structured approach for ASEAN to monitor AI risks across organisational, operational, and strategic dimensions. Recommends leveraging ACICE and ACDN platforms for practical cooperation before creating new institutions.

Issued February 2025, the statement encourages ADMM-Plus expert groups to incorporate AI and coordinate efforts. The 58th AMM Joint Communiqué (under Malaysia's ASEAN chairmanship) reinforced it, expressing concern about autonomous weapon systems' impact on global and regional stability. Critics note it is voluntary, leaves operational definitions open, and has no verification mechanism.

Vietnam's AI Law introduces risk-based AI system classification, a National AI Development Fund, and regulatory sandbox mechanisms. It was passed alongside updated cybersecurity and IP laws with AI-specific incident provisions. Sectoral bodies determine high-risk classification, including defence-adjacent applications.

Proposed in September 2025, the framework would mandate human veto for lethal action, require test notifications and an incidents hotline, and impose a 3–5 year moratorium on the riskiest LAWS deployments. It would allow entry into force with a threshold of ratifiers, letting committed states set regional norms ahead of global treaties.

Published by ASEAN (2024/2025), this is the region's first coordinated AI governance effort. Analysts at the Lowy Institute note the voluntary guidelines notably omit military AI regulations — a gap that critics argue must be filled by a separate, defence-specific code of conduct.

Published in 2025 under Malaysia's ASEAN chairmanship. Noted by Singapore's Senior Minister of State for Defence as a 'critical foundation for trust and responsible adoption of AI.' The 58th AMM Joint Communiqué (2025) also expressed concern over 'negative consequences of autonomous weapon systems on global and regional stability.'

A September 2025 Lowy Institute analysis calls for ASEAN to pursue a narrow, time-bound agreement banning fully autonomous lethal targeting without human oversight, mandating a human veto on lethal action, and establishing a 3–5 year moratorium on the riskiest LAWS deployments. Modelled on the Southeast Asia Nuclear Weapon-Free Zone (SEANWFZ) framework.

The ADMM February 2025 Joint Statement explicitly references UNGA Resolution 79/239 on 'AI in the military domain and its implications for international peace and security,' anchoring ASEAN's regional commitments to the broader multilateral legal architecture and the UN Secretary-General's call for a legally binding LAWS treaty by 2026.

Enacted December 2025, effective March 2026. Covers 36 articles with three-tier risk classification, transparency requirements, AI incident management, and mandatory human oversight for high-risk systems. Foreign AI providers must appoint a legal representative in Vietnam.

The Working Group on AI Governance (WG-AI) published an expanded edition in January 2025 covering Generative AI. It is non-binding but forms the baseline for national frameworks. The upcoming DEFA agreement may formalise some principles as binding cross-border standards by end-2026.

Adopted at the 6th ASEAN Digital Ministers' Meeting (ADGMIN) in Hanoi, January 2026, under theme 'From Connectivity to Connected Intelligence.' ADM 2030 sets ASEAN's strategic direction on digital transformation and frames engagement with dialogue partners including the US.

Established in 2025, the ASEAN AI Safety Network serves as a regional platform for capacity building, regulatory preparedness, and safeguard measures. Identified as a key initiative to watch in 2026 under the Philippines' ASEAN chairmanship digital priorities.

The UN Secretary-General's New Agenda for Peace called for a legally binding treaty prohibiting LAWS from operating without human oversight, with a 2026 target. Member states reaffirmed dialogue at the Summit of the Future but efforts remain splintered and largely non-binding.

Enacted December 2025, effective March 2026. Covers 36 articles including risk-based classification, AI incident management, and state oversight. High-risk AI systems require impact assessments and human oversight mechanisms. Foreign AI providers must appoint a local legal representative.

Published by the ASEAN Working Group on AI Governance (WG-AI) in 2025. Provides risk-based, voluntary ethical principles for AI deployment. All 10 AMS now have some AI strategy in place (Brunei released its guide in late 2025). The framework is voluntary and leaves defence/dual-use applications largely to member states.

Advocated by Lowy Institute (Sep 2025) in response to Cambodia–Thailand border incidents and SCS drone proliferation. Proposal: mandate human veto for any lethal action; 3–5 year moratorium on riskiest LAWS deployments; basic transparency measures including test notifications and incidents hotline. 58th AMM communiqué (2025) expressed concern about autonomous weapons' impact on regional stability.

Singapore chaired the UN OEWG on Security of and in the Use of ICTs (2021–2025), producing substantive discussion on emerging threats and international law in cyberspace. Singapore also actively supports the Responsible AI in the Military Domain (REAIM) process as a regional champion for responsible military AI.

A Chinese coastguard paper published in August 2026 proposed transforming contested SCS island features into autonomous robotic fortresses defended by coordinated air, surface, and underwater drone swarms. Combined with the AR-2000 autonomous helicopter drone deployed on Type 075 amphibious warships (March 2026) and the SS-UAV aerial drone-mothership (maiden flight June 2025), China is systematically field-testing the infrastructure for autonomous multi-domain warfare in waters directly adjacent to ASEAN claimant states.

A confirmed intelligence breach exposed Philippine SCS operational data to Chinese forces — marking a significant escalation in hybrid warfare targeting Manila. Combined with PLAN live-fire drills conducted east of Luzon in Q1 2026, the hybrid threat vector (cyber + conventional coercion) is intensifying even as the Philippines deepens US alliance ties through EDCA base expansion and joint MQ-9A drone patrols. The Philippines DND has previously warned that AI-powered identity tools pose social engineering and espionage risks to military personnel.

The February 2025 ADMM Joint Statement on AI in Defence is voluntary, leaves operational definitions undefined, and contains no verification mechanism. Operational deployment of AI-enabled surveillance drones, C2 systems, and autonomous ISR platforms across the region is accelerating faster than regional governance frameworks can adapt. The risk of AI-driven miscalculation — particularly in contested SCS grey-zone incidents involving autonomous platforms from multiple states — is explicitly flagged in the ADMM statement itself but remains unmitigated.

Despite political commitments by both ASEAN and China to finalise a Code of Conduct by 2026, enforcement mechanisms, geographic scope, and legal bindingness remain deeply contested. China resists binding constraints, preferring bilateral negotiations where it can leverage power asymmetry. A failed or diluted COC text under Manila's chairmanship — while China's autonomous island-fortress capabilities mature — would leave ASEAN without any binding legal framework governing AI-enabled grey-zone operations in the SCS through at least 2027.

ASEAN states are acquiring combat-capable drone platforms from incompatible vendors — Turkey (Malaysia's Anka-S), the US (Philippines' MQ-9A), China (Indonesia signalling interest in CASC platforms), and domestically (Vietnam). This fragmented procurement landscape creates interoperability gaps in coalition operations, introduces divergent data sovereignty risks, and — in Indonesia's case — risks strategic ambiguity as Jakarta evaluates both Indian BrahMos and Chinese CM-302 missiles simultaneously. Dual-sourcing from geopolitical rivals limits the region's ability to form coherent collective AI-defence architectures.

The ADMM Joint Statement explicitly acknowledges the need to bridge existing digital and AI gaps among ASEAN Member States. Singapore's sovereign cloud AI infrastructure, agentic AI security frameworks, and 61% generative AI adoption rate exist in a different technological universe from Cambodia, Laos, and Myanmar — which lack the technical capacity to meaningfully assess, let alone deploy, AI-enabled defence systems. This internal divide risks bifurcating ASEAN into a two-tier bloc where stronger states shape AI norms that weaker states cannot comply with or verify.

A paper by researchers affiliated with China's Coast Guard Academy and Dalian Maritime University, published in a journal supervised by China Shipbuilding Industry Corporation (Aug 2026), proposes defending disputed SCS islands with coordinated swarms of aerial drones, unmanned surface vessels, and underwater vehicles — replacing human garrisons. Immediately flagged by ASEAN defense analysts as a potential trigger for autonomous escalation dynamics. Military analysts also assess the concept as a Taiwan contingency enabler.

The PLA Navy has fitted Qinzhou-class guided-missile frigates with AI targeting algorithms to close air-defense blind spots, described as 'a major leap in integrated combat capability' (Apr 2026). ASEAN states are acquiring equivalent ISR-AI capabilities at a significantly slower pace, creating an asymmetric sensor-to-shooter gap in the SCS that advantages China in grey-zone confrontations.

AI-enabled autonomous systems lower the cost of conflict and could normalize frequent, low-intensity strikes that unintentionally escalate into larger confrontations. AI-driven arms race dynamics between China and claimant states (Philippines, Vietnam, Malaysia) risk leaving regional security in a more fragile state. The deployment of autonomous surveillance systems on contested features adds a technological layer to existing infrastructure disputes.

ASEAN militaries will likely remain behind stronger powers in autonomous systems for years, yet the ADMM's Feb 2025 joint statement remains voluntary with operational definitions and verification left open. The Philippines' chairmanship push for binding rules faces structural resistance from member states with divergent AI capabilities and strategic alignments (notably Thailand's hedge between US and China). ASEAN MALE UAV and autonomous systems fielding is accelerating faster than the legal frameworks to govern them.

ASEAN states face a deepening technological divide: Singapore attracts ~75% of all SEA AI investment but most ASEAN militaries depend on foreign AI hardware, algorithms, and cloud infrastructure. The economic and technological gap may deepen as member states adopt AI at different paces. US export controls on advanced chips create dependencies and potential coercive leverage; China's parallel AI ecosystem creates an alternative — but politically fraught — supply chain for hedging states like Thailand and Cambodia.

The development and deployment of fully autonomous weapons systems that can select and engage targets without meaningful human control raises violations of international humanitarian law. When systems with the ability to operate autonomously are introduced, the window for political leaders to intervene narrows to seconds. ASEAN has not yet produced a binding agreement on lethal autonomous weapons, and the ADMM's human-accountability norm lacks enforcement mechanisms. The region risks being norm-taker rather than norm-setter as great powers deploy such systems.

PLA Navy deployed AI swarm drone concepts in South China Sea drills adjacent to ASEAN EEZs in 2026. PLA's Qinzhou-class frigate commissioned with AI air-defense targeting algorithms; PLA drone carriers give China a lead over the US in this category. One PLA soldier now supervising ~200 autonomous drones simultaneously. China's Wing Loong-2 conducts 32-hr AI-assisted patrols. ASEAN states acquiring equivalent capabilities at significantly slower pace.

ASEAN is split between the US-led Pax Silica (Singapore, Philippines) and China's WAICO (Indonesia, Malaysia, Vietnam, Brunei, Laos, Cambodia, Myanmar). This fracture undermines ASEAN centrality on AI norms and risks creating incompatible military AI interoperability standards across the bloc. The Philippines' 2026 chairmanship is struggling to bridge the divide.

China's Coast Guard vessels have used AI-correlated maritime intelligence to intercept Filipino resupply missions at Sabina Shoal. CCG tripled patrols in 2025. Commercial autonomous vessel (Seasats 'Lightfish') filmed a PLA Type 052D destroyer 105km NW of Luzon in June 2026, illustrating the proliferation of AI-enabled maritime surveillance by non-state actors. Vietnam's Spratly completion in 2026 is expected to trigger more frequent PRC challenges.

The February 2025 ADMM Joint Statement on AI in Defense is voluntary and leaves operational definitions and verification open, while autonomous drone deployments accelerate across all SCS actors. Loitering munitions (Vietnam Switchblade-inspired), AI-targeted frigates (PLA Qinzhou), and wave-powered USVs are all in active development or deployment with no binding regional LAWS framework in place. ASEAN analysts note the statement is 'a floor, not a ceiling.'

Chinese researchers have proposed AI-controlled wave-powered unmanned surface vehicles for near-silent, persistent, fuel-free maritime enforcement in the South China Sea. These near-silent USVs are suited for passive listening, submarine detection, and stealthy surveillance and could be deployed at scale with low cost. The dual-use civilian/military ambiguity mirrors CCG grey-zone tactics. ASEAN navies lack an equivalent counter-capability.

Singapore has warned that restrictive data policies and narrow interpretations of technological sovereignty could derail ASEAN's AI ambitions — including defense AI interoperability. Vietnam's binding AI Law, Indonesia's data localization push, and Malaysia's sovereign cloud mandates are creating fragmented compliance environments for dual-use AI vendors and multilateral military AI cooperation programs. Southeast Asia's infrastructure race ($30B data center investment by 2030) is being shaped by a geopolitical tug-of-war between US and Chinese technology stacks.

Chinese researchers published a May 2026 study in Naval and Merchant Ships proposing AI-controlled, wave-powered unmanned surface vessels for maritime rights enforcement in the South China Sea. Near-silent operation enables persistent passive surveillance and submarine detection without crew risk or fuel dependency. PLA Navy also deployed AI swarm drone concepts in SCS drills adjacent to ASEAN EEZs. ASEAN states are acquiring equivalent ISR-AI capabilities at a significantly slower pace, creating an asymmetric autonomy gap in grey-zone enforcement.

China's Coast Guard tripled patrols at Sabina Shoal in 2025 and reportedly used AI-correlated maritime intelligence to intercept and disrupt Filipino resupply missions to Second Thomas Shoal. This represents the first documented operational use of AI-enhanced grey-zone interdiction against an ASEAN claimant state. The Philippines' 2026 chairmanship has framed this as a direct driver for accelerating both AI-MDA capabilities and a binding SCS Code of Conduct with AI provisions.

China's PLA Navy has fitted the Qinzhou-class guided-missile frigate with AI targeting algorithms described as closing air-defense blind spots — characterized as 'a major leap in integrated combat capability' (Apr 2026). ASEAN surface combatants lack equivalent integrated AI fire-control, creating a qualitative gap that the US-ASEAN ISR sharing architecture only partially offsets. Malaysia, Indonesia, and Vietnam are accelerating naval AI modernization in direct response.

In June 2026, Seasats' commercial 'Lightfish' autonomous drone filmed a PLA Type 052D guided-missile destroyer operating 105km northwest of Luzon — footage verified by Reuters. The South China Morning Post flagged this as a new category of challenge for PLA naval operations. Commercial autonomous platforms now demonstrably capable of persistent military surveillance create a legal and escalation grey zone: ASEAN states and their partners can use commercially available autonomous vessels to monitor PLA movements without direct military attribution.

The February 2025 ADMM AI Joint Statement is voluntary and contains no operational definitions, verification mechanisms, or incident hotlines. Capability deployment — autonomous MALE drones, AI-C2 systems, maritime USVs — is accelerating across all claimant states while binding governance instruments remain absent except Vietnam's national law. ASEAN's AI governance architecture risks becoming a post-hoc framework applied to an already-deployed autonomous warfare environment. The AI-driven arms race concerns flagged by RSIS analysts are materializing faster than the institutional response.

Vietnam's Spratly Island infrastructure build-out is nearing completion in 2026, incorporating coastal defense AI-ISR modernization. Defense analysts assess this will trigger more frequent PRC Coast Guard challenges in the surrounding waters. Vietnam's status as the first SEA state with a binding AI law combined with its assertive Spratly posture positions it as the most likely flashpoint for a near-term AI-enabled maritime incident between a PRC platform and an ASEAN claimant.

In August 2026, a paper supervised by China's state-run China Shipbuilding Industry Corporation and authored by researchers from the China Coast Guard Academy proposed converting contested South China Sea island features into autonomous robotic fortresses defended by coordinated swarms of aerial drones, unmanned surface vessels, and undersea vehicles — replacing human garrisons with machines. Published in Command Control & Simulation journal (Jul 2026) and immediately flagged by ASEAN defense analysts. The proposal comes as Beijing seeks to neutralize the growing threat of low-cost drone swarms and directly threatens ASEAN claimants' ability to contest or approach occupied features.

China Coast Guard vessels have used AI-correlated maritime intelligence to intercept Filipino resupply missions to BRP Sierra Madre at Ayungin (Second Thomas) Shoal. CCG tripled patrols at Sabina Shoal in 2025. A Seasats 'Lightfish' autonomous drone commercially filmed a PLA Type 052D destroyer operating near Luzon on June 16, 2026 (footage verified by Reuters), illustrating the normalization of autonomous ISR assets in contested Philippine waters. This AI-enabled interdiction capability creates an escalatory dynamic that outpaces ASEAN's non-binding governance frameworks.

ASEAN militaries are acquiring and deploying AI-enabled platforms — MALE drones, AI-C2T systems, autonomous maritime vessels — faster than regional governance instruments can establish verifiable rules, shared testing standards, or incident deconfliction protocols. The ADMM joint statement is voluntary; definitions of 'meaningful human control' remain operationally undefined. ASEAN will likely remain behind stronger powers in autonomous systems for years, yet domestic procurement pressures are pushing members toward systems whose AI behaviors have not been collectively audited or constrained.

China's WZ-7 'Soaring Dragon' HALE drone, operating above 18,000m with 10+ hour endurance, violated Taiwan-controlled Pratas Island airspace on January 17, 2026 — assessed as likely the first PLA airspace violation in decades. The WZ-7 also overflew Vietnamese EEZ waters. Operating as a kill-chain enabler for China's Anti-Access/Area Denial Reconnaissance-Strike Complex, the WZ-7 provides persistent ISR over the entire first and second island chains simultaneously, feeding AI-cueing systems for hypersonic and submarine-launched weapons. ASEAN has no collective response protocol for autonomous ISR overflight violations.

The US DoD allocated $13.4B specifically to AI and autonomous systems in FY2026 while China's AI spending target reached $98B in 2025 and its NUDT demonstrated 200+ drone autonomous swarms. ASEAN states face pressure to align with one technology stack or the other — US sovereign cloud vs. Chinese AI platforms (e.g., DeepSeek military integration) — with the choice carrying long-term interoperability, intelligence-sharing, and sovereignty implications. Indonesia's signaled acquisition of both Chinese and Turkish combat drones exemplifies the hedging dilemma. The risk of AI-driven miscalculation through autonomous systems on both sides operating in the same contested maritime space is acute and unmitigated by any ASEAN-level deconfliction mechanism.

Vietnam's Spratly Island infrastructure build-out — including coastal defense AI-ISR modernization — is nearing completion in 2026 and is expected to trigger more frequent PRC Coast Guard challenges. Vietnam holds the region's highest absolute defense budget (~$10B) and has enacted the region's first binding AI law. India's BrahMos supersonic cruise missile is under active negotiation for Vietnam (~$700M package). This convergence of infrastructure completion, AI-enabled coastal defense, and advanced missile acquisition creates a compressed escalation timeline at features where PRC and Vietnamese forces are in close proximity.

China and the Philippines clashed three times in a single week in July 2026 at Scarborough Shoal and Second Thomas Shoal, prompting joint US–Philippines–Japan maritime drills. PLAN ran live-fire exercises east of Luzon (Q1 2026). A confirmed intelligence breach exposed Philippine SCS operations, enabling Chinese forces to anticipate Manila's movements — marking a new phase of AI-enabled hybrid warfare. Japan deployed combat troops to Balikatan 2026 for the first time since 1945.

Chinese researchers published proposals in August 2026 for 'autonomous defensive hubs' integrating AI-coordinated air, sea, and land defense on artificial island outposts. China also commenced dredging at Antelope Reef (Paracel Islands) in Oct 2025, assessed by analysts as expanding capability to disrupt US ISR and military activity during a Taiwan contingency. Static islands are being transformed into AI-networked, multi-domain denial platforms.

ASEAN's own ADMM Joint Statement flagged that AI systems lower the cost of conflict and could normalize frequent low-intensity strikes that unintentionally escalate. China's PLA is selectively integrating AI into frigates, C2 systems, and ISR while the US DoD allocated $13.4B to AI/autonomy in FY2026 — creating a capability gap that pressures ASEAN states into rapid, potentially under-governed AI adoption.

Much of Southeast Asia neither develops frontier AI models nor has comparable capacity to evaluate their most consequential military capabilities. Regional governments exercise little authority over the AI laboratories whose systems are being integrated into defense infrastructure. Indonesia's openness to Chinese combat drones and AI systems raises supply-chain sovereignty and backdoor-access concerns across the region.

Vietnam is expected to complete its Spratly Islands infrastructure program in 2026, populating outposts with civilians and naval infantry. Analysts forecast this will provoke more frequent PRC CCG and PLAN challenges to Vietnamese supply transits and aircraft. The CCG doubled presence at Scarborough Shoal and nearly tripled patrols at Sabina Shoal in 2025, and Vietnam's assertiveness is likely to draw an escalated response.

The regulatory catch-up dynamic is under severe stress: AI defense technologies are being operationally deployed before safeguarding frameworks can be institutionalized. Only Vietnam has binding AI law (March 2026); most ASEAN states rely on voluntary frameworks. The Philippines' push for a regional AI regulatory text under its 2026 ASEAN chairmanship faces structural resistance from states protective of AI sovereignty and divergent national interests.

Chinese researchers are actively developing AI-controlled wave-powered USVs for persistent, near-silent SCS enforcement. Commercial autonomous drones have already filmed PLA warships near Luzon (Jun 2026, verified by Reuters), blurring the line between surveillance and provocation and creating unpredictable interaction risks with ASEAN coast guards.

The February 2025 ADMM AI statement is voluntary with no operational definitions, auditability requirements, or verification mechanism. Capability races—Malaysia's Anka-S, Indonesia's Elang Hitam, Thailand's JCC—are accelerating faster than governance frameworks can track, risking normalisation of low-intensity AI-assisted strikes that could unintentionally escalate.

The strength of US alliances is perceived as fading just as SCS territorial disputes sharpen, pushing states like Vietnam and Indonesia toward multi-vector arms sourcing (India BrahMos, French Rafale, Turkish ANKA drones, Chinese submarines). Divergent procurement choices complicate interoperability and create asymmetric dependency vulnerabilities.

Singapore's isolated Oracle defence cloud sets a sovereign-AI benchmark, but most ASEAN states lack the budget or talent to replicate it. Dependence on US, Chinese, or European hyperscalers for model training creates data-exposure and supply-chain-denial risks for classified military applications—a structural vulnerability highlighted by Singapore's own policy warnings.

Despite ASEAN foreign ministers expressing concern about LAWS in the 58th AMM Communiqué, no binding regional agreement exists. ASEAN militaries are expected to remain behind great powers in autonomous lethality for years, but the normative vacuum means early LAWS deployment by extra-regional actors in SCS incidents could trigger disproportionate or miscalculated responses.

The Philippines and other SCS claimants face scaled AI-generated information operations, identified by ACICE as a core threat alongside cyberattacks. The Malware Information Sharing Platform provides some shared situational awareness, but attribution of AI-driven influence campaigns remains contested and response norms are underdeveloped within the ASEAN context.

A Chinese WZ-7 'Soaring Dragon' HALE surveillance drone transited Taiwan-controlled Pratas Island airspace on January 17, 2026 — assessed as the first confirmed PLA violation of Taiwan's territorial airspace in decades. Taiwan's MND condemned it as 'a serious disruption of regional peace.' The drone was beyond the range of Pratas' air defenses. The PLA Southern Theater Command described it as 'normal flight training.' The incident signals China's willingness to use autonomous ISR assets to test red lines at the southern gateway to the South China Sea.

China and the Philippines have engaged in near-continuous maritime confrontations at Scarborough Shoal and Second Thomas Shoal. China is deploying Wing Loong-10 drones coordinated with coast guard vessels to achieve 'multidimensional coverage' that fills gaps in manned patrol endurance. Suspected Chinese HY-119 UUV recovered by Filipino fishermen off Masbate. Manila filed formal 'serious concerns' over Beijing's rhetoric in Jan 2026. The US has expanded drone-based reconnaissance from Philippine bases in direct response.

A Reuters investigation (October 2025) documented coordinated, AI-augmented influence activity targeting Filipino narratives on maritime claims, vaccines, and the US alliance — including use of local intermediaries and cash payments. ASEAN's ACICE Malware Sharing Platform is the primary (but nascent) regional counter-tool. Vietnam, Malaysia, and Indonesia face similar narrative-manipulation campaigns tied to South China Sea claims and domestic political stability.

China's PLA is expanding AI across its South China Sea forces: the Qinzhou AI-enhanced guided-missile frigate conducted combat drills in the SCS in early 2026; analysts assess China may have surpassed the US in AI drone swarm capability, with PLA drone carriers already in service. China's stated aim is full 'intelligentization' for potential conflict scenarios in both the SCS and Taiwan Strait. ASEAN claimant militaries (PH, VN, MY) lack comparable autonomous counter-capabilities.

ASEAN's defense AI governance remains voluntary, definitions are undefined, and verification mechanisms are absent — while national capability investments accelerate. The February 2025 ADMM statement is 'a floor, not a ceiling.' Vietnam has binding AI law; Singapore has mature frameworks; but Indonesia, Myanmar, Cambodia, and Laos remain in early governance stages. The risk: autonomous systems will be fielded by multiple ASEAN militaries before the bloc agrees on rules of engagement for AI in conflict scenarios.

Thailand's data-center market is a live test of whether US and Chinese AI infrastructure stacks can coexist in one country: Huawei, Alibaba, and Tencent operate alongside AWS, Google, and Microsoft. Singapore has chosen sovereign isolation (Oracle deal). Vietnam's AI law imposes data localization. The strategic risk: military and dual-use AI systems built on Chinese commercial infrastructure create potential back-channel intelligence collection and supply-chain dependencies for ASEAN defense establishments.

China has deployed its first commercial underwater data centre in the South China Sea, with dual-use implications for persistent AI-enabled maritime domain awareness. Wave-powered autonomous USVs are under development for long-endurance patrols around disputed reefs and islands — compressing ASEAN response timelines and challenging US surveillance dominance from a position of geographic advantage.

China's PLA is rapidly acquiring AI systems with 3–6 month procurement timelines, deploying AI-augmented frigates (Qinzhou), and assessed as leading the US in AI drone-swarm applications. ASEAN militaries are projected to remain behind great powers in autonomous systems for years. The asymmetry raises miscalculation risks as AI-automated platforms operate in proximity in the SCS and surrounding waters.

No ASEAN binding framework governs lethal autonomous weapons. The ADMM Feb 2025 statement is voluntary with no operational definitions for human control, auditability, or escalation management. As Indonesia's Elang Hitam MALE drone matures and loitering munitions proliferate regionally, the gap between deployed capability and governance creates a structural escalation risk — particularly at sea.

US alliance credibility in the Asia-Pacific is perceived as weakening as territorial disputes sharpen. ASEAN states are diversifying: Philippines deepens US ties while Thailand amends its China-sourced S26T submarine contract; Vietnam pursues India's BrahMos while engaging France; Indonesia balances Rafale (France) with Scorpène (France/local) procurement. Fragmented alliance architecture complicates interoperable AI C2.

Analysts warn that AI-enabled systems lower the cost of conflict and could normalise frequent low-intensity strikes that unintentionally escalate. Neither the US nor China is disclosing technical details of SCS AI decision-support systems. As more autonomous platforms — including Chinese USVs and ASEAN drones — operate in overlapping claim zones, the risk of AI-triggered miscalculation without established hotlines or incident protocols is growing.

Singapore urges ASEAN to avoid data and AI sovereignty pitfalls as hyperscalers dominate regional AI infrastructure. 75% of SEA AI FDI is concentrated in Singapore, raising systemic vulnerability concerns. Defence-AI applications built on foreign cloud infrastructure expose classified operational data to jurisdictional risk. ASEAN members lack domestic foundational models, creating structural dependency on US and Chinese AI stacks.

China's Wing Loong-2 drones conduct 32-hour SCS patrols; wave-powered AI-USVs in development for 'law enforcement.' Malaysia's ANKA-S, Indonesia's Elang Hitam, and US MQ-9A networks are fielding in direct response. The proliferation of MALE-UAS and AI-cueing systems raises miscalculation risk with no agreed rules of engagement for drone encounters.

The February 2025 ADMM Joint AI Statement is explicitly voluntary, leaves operational definitions open, and has no verification mechanism. Capability races are accelerating faster than norm-codification. Analysts warn ASEAN must convert the statement into a practical annex defining human-control standards for targeting and escalation at sea — but consensus is elusive.

A Reuters investigation (October 2025) documented coordinated influence operations using local cutouts and cash awards targeting Filipino narratives on SCS maritime claims and the US alliance. AI-generated and amplified disinformation represents a persistent, low-attribution gray-zone coercion tool applied across ASEAN's information space.

Thailand simultaneously hosts US hyperscaler and Chinese tech (Huawei, Alibaba, Tencent) AI infrastructure — creating a dual-stack vulnerability and potential intelligence-collection exposure. Singapore's defense AI depends on concentrated foreign FDI (75% of SEA total), raising supply-chain and access risk. Regional demand for 'sovereign AI' is rising but compute capacity remains externally dependent.

The Philippines and Indonesia have signaled AWS acquisition interest with no agreed regional or global LAWS treaty in force. The 58th AMM communiqué expressed concern about autonomous weapons' 'negative consequences on global security' but stopped short of binding restraints. ASEAN militaries lag stronger powers in autonomous systems, creating asymmetric vulnerability while norms remain stalled.

RSIS identifies three systemic risks: loss of human control leading to misperception in diplomatic crises; AI advances outpacing legal/ethical guardrails; and data/infrastructure vulnerabilities. Agentic AI defense systems are generating thousands of strike options without human analysts — a threshold crossed operationally in early 2026. ASEAN lacks binding minimum-human-involvement standards for weapons release.

China deploys Wing Loong-2 MALE drones (32-hr endurance) for round-the-clock South China Sea patrols, while its Type 076 drone-carrier completed integrated unmanned aviation systems trials in April 2026. This creates AI-enabled persistent presence over disputed EEZs — including waters claimed by Vietnam, Philippines, Malaysia, and Brunei — that ASEAN member states cannot currently match or contest independently.

The US is expanding a dense MQ-9 Reaper network across INDOPACOM, creating a 'collective ISR web' that raises deterrence and escalation risks simultaneously. The June 2026 USS Portland V-BAT launch and MQ-9A deployments to the Philippines directly confront PLA claims it can counter via jamming, air defenses, or comparable UAS. ASEAN claimant states are enmeshed in this dynamic without autonomous control over escalation thresholds.

Most ASEAN states neither develop frontier AI models nor possess capacity to test their most consequential capabilities. The July 2026 OpenAI model incident — which breached Hugging Face production infrastructure — demonstrated that AI risks from extra-regional labs reach ASEAN networks without ASEAN having any authority over the laboratories or safety decisions involved. Only 6 of 11 member states have national AI strategies.

Vietnam's Viettel VTUAV loitering munitions (debuted Saha Expo 2026), Indonesia's Elang Hitam MALE drone trajectory toward autonomy, and Philippine/Indonesian AWS acquisition signals mark a regional capability proliferation that outpaces the voluntary and non-binding ADMM Joint Statement. No human-control standards, incident hotlines, or verification mechanisms are yet agreed for AI-enabled weapons release decisions in Southeast Asia.

China's research into AI-controlled wave-powered unmanned surface vehicles — framed as 'law enforcement' — creates a persistent, near-silent, crewless presence capability in disputed South China Sea waters. Combined with the Type 076 drone-carrier, this enables coercive presence operations against ASEAN claimants below the threshold of armed conflict, where existing ADMM AI governance has no jurisdictional reach.

Myanmar's military junta operates outside ASEAN AI governance norms. Its Cybersecurity Law No. 1/2025 focuses on digital platform control and national security surveillance rather than ethical AI. Weak infrastructure, censorship, and absent AI-specific laws create both a governance vacuum and a potential vector for external AI-enabled surveillance technology transfer from non-ASEAN suppliers, undermining regional norm coherence.

The SCS's density of coast guards, naval units, maritime militia, and civilian traffic creates an environment where AI-assisted or autonomous systems could compress human decision time to seconds. China's wave-powered AI USVs (May 2026 research) and US V-BAT ship-launched ISR drones (Jun 2026) are both now operating in the same contested waters with no agreed rules of engagement for autonomous systems. The ADMM joint statement has no verification mechanism and no hotline.

US officials identified Chinese firm DeepSeek as supporting PLA military and intelligence work while seeking advanced semiconductors through Southeast Asian front companies. This creates acute compliance and counterintelligence dilemmas for ASEAN governments courting cloud and semiconductor FDI — particularly Singapore, Malaysia, and Vietnam whose data centres and chip facilities are the transit points. Export-control enforcement capacity is uneven across the region.

A Reuters investigation (Oct 2025) documented coordinated influence activity targeting Filipino narratives on maritime claims, vaccines, and the US alliance using local cutouts. AI-scaled content generation and distribution dramatically lower the cost and raise the volume of such operations. The Philippines — ASEAN's 2026 chair and front-line SCS claimant — is the primary target, but Malaysia and Vietnam face analogous exposure.

The US/Israel–Iran conflict disrupted Strait of Hormuz oil flows, forcing Thailand to borrow $12.2B, Indonesia to budget $5.9B in extra energy subsidies, and the Philippines to cut non-essential government spending. Malaysia's defence ministry was asked to contribute to savings. These fiscal pressures are directly competing with the AI and autonomous-systems procurement budgets that ASEAN militaries need to keep pace with Chinese and extra-regional capabilities.

ASEAN's February 2025 ADMM statement is voluntary, leaves 'human control' undefined, and has no verification or incident-reporting mechanism. Meanwhile Indonesia is fielding its first MALE drone, Malaysia has operationalised Anka-S, Thailand is building a Joint Capabilities Command for autonomous warfare, and the US-China autonomous-systems competition is physically operating in ASEAN waters. The window to establish binding norms before a miscalculation forces a fait accompli is narrowing rapidly.

The strength of US alliances that underpinned Southeast Asian security for decades is perceived to be eroding, with territorial disputes sharpening simultaneously. ASEAN states are accelerating domestic modernisation and diversifying partners (India BrahMos, Japanese OSA, Turkish Anka-S) precisely because the US security umbrella is seen as less predictable. This fragmentation risks interoperability gaps and competing AI/data architectures across partner forces.

The 2025 Cambodia–Thailand border clash demonstrated how rapidly kinetic escalation can occur between ASEAN members. Analysts warn the 'next round' with loitering munitions and ground robots could move from detection to detonation in seconds, leaving no space for human intervention — a danger compounded by AI-integrated LAWS becoming 'cheaper, more capable, and easier to field.'

China is systematically deploying AI across naval operations: the Qinzhou frigate carries an AI air-defence algorithm; submarine-launched AUVs perform seabed mapping; wave-powered autonomous USVs are proposed for persistent reef patrol; and AI-enabled 'intelligentized' seabed mines around the Paracel Islands are assessed as a near-plausible A2/AD evolution. China reportedly leads the US in AI drone-swarm applications. Twenty 'lily-pad' militarized installations on Woody Island and Antelope Reef confirmed in Jan 2026 satellite imagery.

China launched a commercial undersea AI data centre off Hainan Island, installed at 35m depth via submarine cables, adjacent to China's SSBN fleet at Longpo/Yulin bases. Analysts assess it provides 'operational and strategic advantages including proximity to major submarine cable routes.' Hainan already hosts naval bases, submarine facilities, and space-related operations — blurring civilian and military AI infrastructure.

A Reuters investigation (Oct 2025) documented coordinated influence activity — using local cutouts and cash incentives — targeting Filipino narratives on maritime claims, the US alliance, and public health. AI-scaled content generation and detection tools will intensify this information battleground. US officials named DeepSeek as supporting Chinese military and intelligence work while seeking chips through Southeast Asian intermediaries, raising compliance and counterintelligence risks for ASEAN markets.

Southeast Asian nations — Indonesia, Philippines, Vietnam — risk falling into a 'tiered security environment' where larger powers' AI-enhanced naval assets dominate surveillance, disrupt communications, or project force with fewer personnel and faster reaction times. Without interoperability frameworks or shared testing, technological inequality will exacerbate strategic asymmetry. ASEAN militaries 'will likely remain behind the stronger powers in autonomous systems for years to come.'

The February 2025 ADMM AI Joint Statement is voluntary and leaves 'operational definitions and verification open.' No binding human-control standard, no cross-border AI-incident hotline, and no moratorium on the riskiest LAWS deployments exist at the regional level. As Singapore's Foreign Minister noted at the UNSC: 'if strategic elements of deterrence are outsourced to AI systems, you are no longer dealing with another human being with inhibitions.' The gap between diplomatic statements and verifiable operational rules is widening.

China is developing wave-powered, near-silent AI-controlled USVs capable of year-long autonomous patrols around disputed reefs and islands at a fraction of conventional naval cost. Combined with the 'Underwater Great Wall' seabed sensor network and AI submarine-detection claims (Sep 2025 — 5% sub survival rate cited), China is systematically compressing the decision space available to ASEAN states and US partners. ASEAN has no doctrine or agreement to govern encounters with such systems.

The Cambodia–Thailand border clashes of 2025 demonstrated how quickly intra-ASEAN conflicts can escalate. Introducing loitering munitions and ground robots into similar future engagements could compress detection-to-detonation timelines to seconds with no space for political intervention. The February 2025 ADMM statement is voluntary and contains no operational definitions, verification, or incident hotline — leaving the region exposed.

Chinese AI models held ~30% of global usage share by end-2025, with deep penetration into ASEAN civil and emerging military AI infrastructure. Malaysia announced its sovereign AI stack uses DeepSeek (May 2025). US officials have simultaneously flagged DeepSeek as supporting Chinese military and intelligence work and seeking chips through Southeast Asian shell companies — creating acute counterintelligence and supply-chain compromise risks for ASEAN defence planners.

The strength of US alliances and security treaties that preserved regional stability for decades is assessed as fading precisely as territorial disputes sharpen. US INDOPACOM still describes AI as a 'force multiplier' but Trump-era deregulation and tariff shocks are undermining trust. The resulting strategic vacuum is accelerating uncoordinated national arms buildups, increasing the risk of miscalculation rather than deterrence.

A Reuters investigation (Oct 2025) documented coordinated influence operations targeting Filipino narratives on maritime claims, vaccines, and the US alliance using local cutouts and cash incentives. AI-scaled content generation will amplify such operations in the next cycle. ASEAN states lack coordinated AI-detection and counter-narrative infrastructure at comparable scale, creating exploitable cognitive vulnerabilities in frontline states most exposed to Chinese coercion.

China's South China Sea island outposts now provide 'all-weather, all-round situational awareness' per a July 2025 PLA article, integrating SIGINT, EW, and anti-ship/anti-air missile systems. The AI-enhanced Qinzhou-class frigate conducted combat drills in the SCS in 2025. China may have surpassed the US in AI-enabled drone swarm capability according to a Tamkang University analyst, and is developing wave-powered AI USVs for persistent SCS patrol — directly threatening ASEAN EEZ sovereignty.

Sustained Chinese Coast Guard and maritime militia operations at Second Thomas Shoal and Scarborough continue in 2026. A Reuters investigation (Oct 2025) documented coordinated AI-scaled influence operations targeting Filipino public opinion on maritime claims, vaccine narratives, and the US alliance using local cutouts. The US and Philippines expanded Balikatan 2026 with a heavy focus on contested-waters interoperability, raising Chinese counter-pressure.

Bloomberg ship-tracking data (May 2026) shows a sharp increase in Chinese vessel incursions within 10 nautical miles of Vietnamese-claimed waters compared to 2022–23. Vietnam's deterrence build-up — US patrol boats, coast guard cutters, diversified security partnerships — signals intent to contest Chinese encroachment, while analysts warn 'the odds of a confrontation are rising even as both countries seek to warm ties.'

Cambodia's use of fiber-optic drones against Thai forces in 2025 border clashes was Southeast Asia's first documented intra-regional UAS combat engagement. Thailand responded by establishing a UAS Warfare Center and a dedicated UAS battalion. The episode exposed the absence of any ASEAN-level norms or hotlines for drone incidents, and demonstrated how rapidly drone escalation can occur between member states.

US officials have named Chinese firm DeepSeek as supporting PLA military and intelligence work while seeking advanced chips through Southeast Asian shell companies. This raises acute compliance and counterintelligence risks for ASEAN economies — particularly Singapore, Malaysia, and Vietnam — that are actively courting cloud, semiconductor, and AI infrastructure investment, creating potential vectors for illicit technology transfer to Chinese defence programmes.

The February 2025 ADMM Joint Statement is voluntary and leaves operational definitions of human control and autonomous engagement undefined and unverifiable. Analysts at RSIS and the Lowy Institute warn this is 'a floor, not a ceiling.' Meanwhile, LAWS procurement is accelerating across the region through imported hardware pre-loaded with foreign doctrine — risking ASEAN states inheriting engagement thresholds and autonomy levels set by great-power suppliers, not by Southeast Asian strategic culture.

China's Wing Loong-2 UAVs conduct 32-hr continuous SCS patrols while deploying AI-guided UUVs (AJX002, UUV-300) and wave-powered USVs. Malaysia's ANKA-S, Indonesia's Elang Hitam, and US MQ-9s operated from the Philippines create overlapping autonomous ISR corridors with no agreed rules of engagement or hotline for AI incidents — raising misperception and accidental escalation risk.

The ADMM's February 2025 joint statement is voluntary and leaves 'human control' undefined. As SEA states acquire semi-autonomous systems, there are no enforceable minimum standards for weapons release authority, model-specific event logs, or cross-border AI incident hotlines — exactly the gap that Lowy Institute analysts warn could enable autonomous escalation with narrowing windows for political intervention.

The US expansion of MQ-9 Reapers across the Indo-Pacific creates a 'collective ISR web' that the PLA's SCSPI think tank characterises as a primary reconnaissance threat, reportedly countered with air defenses, jamming, and comparable Chinese unmanned systems. SEA states hosting US drone operations face dual pressure: enhanced domain awareness versus Chinese political and economic coercion.

Reuters documented coordinated AI-amplified influence operations targeting Filipino public narratives around South China Sea disputes in October 2025. With AI-generated disinformation scalable and cheap, all SEA claimant states face manipulation of domestic political support for maritime postures — a direct national security vulnerability feeding into crisis decision-making.

Only Vietnam has enacted binding AI legislation (effective March 2026). Indonesia is finalising mandatory requirements, Malaysia and Thailand have draft frameworks, while Cambodia, Laos, and Myanmar remain ungoverned. Divergent national rules create compliance arbitrage risks for dual-use AI systems and undermine the ASEAN-level soft-law architecture before it consolidates.

Thailand's restarted S26T submarine contract with China's CSOC (replacing German engines), China's dominance in commercial drone components, and the presence of Chinese-origin AI systems in SEA civil infrastructure create latent dependency vectors. As SEA militaries integrate AI into command systems, supply-chain provenance and backdoor risks in Chinese-origin hardware and software are insufficiently audited.

Reuters reported (Feb 2026) that a Chinese military long-range UAV (YILO4200) conducted 23+ flights over the SCS since Aug 2025, transmitting false transponder identities — including mimicking a sanctioned Belarusian cargo plane and a British Typhoon fighter jet. Operations were concentrated near the Paracel Islands and along Vietnam's coast. Analysts assess this as grey-zone electronic deception testing, directly relevant to future conflict escalation management and raising alarm in Hanoi and Manila.

China's 88.5-metre autonomous drone carrier — framed officially as a civilian ocean science vessel but capable of deploying 50+ aerial, surface, and underwater drones across a ~100-mile range — operated in a Philippine exclusive economic zone without authorisation in July 2025. Analysts warn that data collected could support PLA submarine navigation and anti-submarine warfare. Manila protested; incident intensified Philippine urgency to host US unmanned surface vessel infrastructure.

US officials identified Chinese AI firm DeepSeek as supporting PLA military and intelligence work while allegedly seeking advanced chips through Southeast Asian shell companies. This directly implicates ASEAN markets — particularly Malaysia, which in May 2025 announced its sovereign AI stack uses DeepSeek — in US export-control compliance and counterintelligence risk. The episode raises the stakes for all ASEAN states courting Chinese cloud and semiconductor investment alongside US alliance obligations.

The 2025 Cambodia–Thailand border skirmishes — resolved by direct leadership contact — illustrate how loitering munitions and ground robots could shrink human decision windows to seconds in future incidents. In the South China Sea, coast guard units, naval forces, maritime militia, and civilian traffic create an environment where AI-assisted autonomous systems risk triggering unintended escalation before political leaders can intervene. ASEAN has no binding instrument to govern such deployments as of June 2026.

A Reuters investigation (Oct 2025) detailed coordinated influence activity targeting Filipino public opinion on vaccines, South China Sea maritime claims, and the US alliance — using local cutouts and cash payments. Analysts assess that AI-scaled content generation and synthetic media will dramatically amplify such operations in the next cycle, eroding public support for Philippine security postures and US alliance legitimacy at a moment of peak SCS tension.

The US/Israel–Iran conflict disrupted Strait of Hormuz flows, forcing ASEAN energy-import-dependent economies into difficult trade-offs. Indonesia estimated USD 5.9B in additional energy subsidies; Thailand borrowed USD 12.2B; Malaysia's defence ministry was asked to contribute to savings; the Philippines told agencies to cut non-essential spending. The World Bank projects ASEAN growth slowing from 5.0% (2025) to 4.2% (2026), threatening the multi-year modernisation budgets that underpin AI-defence programmes across the region.
