China warns over Nvidia chip curbs

Highlights

China's foreign ministry criticizes U.S. for using espionage allegations to justify technology restrictions, reiterating opposition to broad national security measures affecting Nvidia exports.
Reports of Nvidia CEO Huang's personal links to a Chinese intelligence asset intensify risk of stricter U.S. export controls, threatening the current chip trade truce set to expire January 10.
Chinese tech stocks fall sharply Thursday, with Alibaba down 6.8% and Hong Kong-listed Z.ai and MiniMax dropping over 9% and nearly 8% respectively, amid Nvidia controversy.

Beijing response and export control concerns

As reported by Financial Times, China’s foreign ministry says the U.S. should stop creating what it calls espionage allegations as justification for a technological blockade, after questions intensify over Huang’s links to an alleged Chinese intelligence asset.

Mao Ning, a foreign ministry spokesperson, tells reporters in Beijing that China’s technological progress depends on independent innovation and open co-operation, and says Beijing remains willing to build constructive strategic stability with the U.S. She also says she is unfamiliar with allegations that a Chinese university bought Nvidia H200 chips in breach of existing export controls, while reiterating opposition to what China sees as an overly broad U.S. national security rationale and unfair pressure on Chinese institutions.

Nvidia’s board is considering Huang’s future after reports of his romantic relationship with a company executive and, separately, his admitted affair with an executive at an Nvidia customer whom U.S. officials believe is a Chinese intelligence asset. The fallout is complicating an already restricted chip trade in which Nvidia is barred from selling its most advanced products to China, while Beijing is also pursuing semiconductor self-sufficiency and maintaining its own constraints on Nvidia chip imports.

Market impact and trade implications

The controversy is feeding concern that Washington could harden its stance on China technology exports just as the two countries try to preserve a temporary trade truce. U.S. President Donald Trump and Chinese leader Xi Jinping are expected to meet in Shenzhen next week during the Asia-Pacific Economic Cooperation summit, while the current truce, agreed in South Korea last year, is due to expire on January 10.

Analysts and academics say the episode risks strengthening the hand of officials who favour wider export controls. Zhu Feng of Nanjing University says the controversy could be used to demonise Trump’s China policy, while an adviser to Beijing policymakers says there is concern the allegations may influence Washington and provide ammunition to China hawks.

Homin Lee, senior macro strategist at Lombard Odier, says the furore already has a clear impact on Washington dialogue over export controls and adds pressure to China’s technology ecosystem, which still relies heavily on Nvidia chips and its Cuda software platform for AI model development. Chinese technology shares fall on Thursday, with Alibaba down 6.8%, while Hong Kong-listed large language model providers Z.ai and MiniMax drop more than 9% and nearly 8%, respectively.
