China on Friday condemned renewed US calls to tighten semiconductor export controls to the country, citing the ongoing controversy surrounding Nvidia’s leadership and alleged technology diversion.
Beijing’s foreign ministry spokesperson Mao Ning stated that additional restrictions would disrupt global supply chains and harm bilateral economic relations. Her remarks followed reports that US lawmakers are pushing for stricter limits on chip exports to China in response to the Nvidia scandal.
Singapore barred Alice Huang, a businesswoman linked to the scandal, from re-entering the city-state on Thursday, while US intelligence documents alleged her ties to China’s Ministry of State Security. Prosecutors in Singapore also filed additional fraud charges against five individuals in a case involving servers that may have contained Nvidia chips destined for Malaysia.
Immediate Actions and Core Facts
China opposes new US chip export controls
China’s foreign ministry rejected proposals to expand restrictions on semiconductor exports to China, calling such measures counterproductive. Mao Ning emphasized that the US and China should uphold agreements between their leaders to maintain stable trade relations.
Singapore enforces restrictions amid Nvidia scandal
Singapore’s Ministry of Home Affairs barred Alice Huang from re-entering the country, citing ongoing investigations into alleged fraud involving servers that may have contained Nvidia chips. A separate case involves $390 million in unauthorized server exports to Malaysia, with prosecutors filing 41 new charges on Friday.
Deeper Context and Policy Implications
US Lawmakers Push for Stricter Chip Controls
US House Speaker Mike Johnson publicly supported tighter export controls on AI chips to China, framing the issue as a national security priority. Johnson stated that Congress is developing a consensus on limiting chip sales, though no formal policy changes have been announced.
Nvidia’s Leadership Scandal Deepens
Nvidia co-founder Jensen Huang resigned on Thursday following reports of an extramarital affair with Alice Huang, a former executive at Singapore-based Megaspeed International. The scandal has intensified scrutiny of alleged efforts to bypass US export restrictions on advanced AI chips.
Military Ties Raise Concerns Over Chip Purchases
A Chinese university with links to the People’s Liberation Army (PLA) purchased Nvidia H200 chips despite US export controls. Northwestern Polytechnical University (NWPU) acquired two H200 chips in September and October, totaling 1.67 million yuan ($251,000). The university, which has been blacklisted by Washington, has denied any wrongdoing.
US Export Rules and Enforcement Gaps
The US Commerce Department relaxed some chip export restrictions in January, allowing sales of Nvidia’s H200 chips to China under case-by-case approval. However, enforcement remains a challenge, with reports suggesting some suppliers may have facilitated unauthorized transfers to military-linked entities.
Singapore’s Role in the Global Chip Trade
Singapore serves as a major hub for Nvidia’s regional sales, with 22% of the company’s revenue tied to the city-state in the fiscal quarter ending July 2025. US officials have increasingly scrutinized Singapore’s role in potentially facilitating the rerouting of restricted chips to China, though local authorities deny systemic failures.
Singapore’s Ministry of Trade and Industry noted that less than 1% of Nvidia’s chips physically delivered to the country were ultimately used there, suggesting most were transshipped elsewhere.
