AI Chip War 2026: How Singapore & Malaysia Got Caught Between US and China

New guidance from the US Department of Commerce issued in late May 2026 has tightened licensing requirements for Nvidia’s most advanced processors, including its Blackwell series, closing a loophole that let Chinese firms acquire restricted chips through overseas subsidiaries — and putting Singapore and Malaysia squarely in Washington’s crosshairs as the two Southeast Asian hubs most exposed to diversion risk (NaturalNews).

A Trillion-Dollar Market, and a Widening Grey Zone

Under the current three-tier US export framework, Singapore and Malaysia sit in “Tier 2” alongside roughly 120 other countries, including India and the UAE, meaning firms there must obtain individual licences or validated end-user authorisation before accessing the most advanced AI chips (Asia Times). That has not stopped both markets from becoming critical waypoints in the global AI supply chain: Singapore alone accounted for roughly one-fifth of Nvidia’s $215.9 billion in revenue for the fiscal year ended January 2026, making it the company’s second-largest market after the United States.

The scale of the enforcement challenge became public in May 2026, when the US Department of Justice charged three individuals connected to a technology supplier in a scheme involving roughly $2.5 billion worth of Nvidia-powered servers, allegedly routed to Chinese brokers using dummy replicas to defeat physical audits (Model Diplomat). That case echoes an August 2025 indictment involving chip shipments transiting through Malaysia and Singapore en route to Hong Kong, underscoring how the region has become a persistent pressure point for US export enforcement.

Malaysia Moves First, Thailand Lags Behind

Regional responses have diverged sharply based on exposure and regulatory capacity. Malaysia acted earliest, introducing a mandatory Strategic Trade Permit in July 2025 covering the export, transshipment and transit of high-performance US-origin AI chips — a move widely read as Kuala Lumpur choosing to tighten oversight rather than risk its reputation as what one Eco-Business analysis calls a “weak link” in the compliance chain (Eco-Business).

Thailand has proven more exposed. In May 2026, US authorities publicly flagged a Bangkok-based firm tied to the country’s national AI initiative for allegedly helping divert billions of dollars’ worth of Nvidia-powered servers to Chinese companies including Alibaba — a case that illustrates how national AI ambitions and export-control compliance can pull governments in opposing directions.

Beijing’s Answer: Building Around the Restrictions

China’s response to tightening controls has increasingly been to accelerate domestic substitution rather than simply seek workarounds. Nvidia CEO Jensen Huang told CNBC in May that he had effectively “conceded” the Chinese data-centre market to Huawei, with the company now assuming zero data-centre chip revenue from China going forward — a remarkable admission given that the Chinese market generated an estimated $12–15 billion in H20 chip sales as recently as 2024 (Model Diplomat).

China’s own supercomputing ambitions received a symbolic boost in June 2026 when the domestically built LineShine supercomputer, developed at Shenzhen’s National Supercomputing Center, reclaimed the top spot on the global TOP500 ranking, surpassing the US-built El Capitan system. Analysts tracking China’s fifteenth five-year plan note that Beijing has explicitly directed its AI sector to develop “extraordinary measures” to defeat export controls, with domestic players Huawei, Cambricon and SMIC forecast to reach at least 50% market share within China by the end of 2026.

Why Southeast Asia Cannot Simply Pick a Side

Chatham House’s assessment of the broader export-control strategy is unusually blunt: rapid global demand growth for AI compute makes enforcement extraordinarily difficult, and countries like Malaysia and Singapore have become de facto grey markets whether or not their governments intend that outcome (Chatham House). The US Chip Security Act, working its way through Congress, aims to close some of these gaps by requiring companies to verify that chips remain in authorised locations — but even proponents acknowledge that legislation alone cannot fully police a supply chain running through dozens of jurisdictions with varying regulatory capacity.

For Singapore and Malaysia, the dilemma is structural rather than merely diplomatic: both governments actively court data-centre investment from American and Chinese firms alike, because both flows generate genuine economic value, jobs and technology transfer. Neither wants to be forced into an exclusive alignment with Washington or Beijing on chip policy, yet the political and legal risk of appearing to enable diversion is rising sharply with each new DOJ indictment. The likeliest trajectory for the rest of 2026 is not a clean resolution but an intensifying game of regulatory whack-a-mole, with Southeast Asian governments tightening rules just fast enough to avoid becoming Washington’s next enforcement headline, without fully closing the door on Chinese capital.
