Warren, Banks push chip curbs after Nvidia spy scandal

Reports that Nvidia CEO Jensen Huang was the target of a Chinese intelligence operation are giving new momentum to congressional efforts to restrict AI chip sales to China. In a joint statement on November 9, Sens. Elizabeth Warren (D-Mass.) and Jim Banks (R-Ind.) said Huang's "confirmation of a relationship with a suspected spy for China's intelligence service makes these national security concerns even more urgent." They urged Congress to "pass key bills like the AI Overwatch Act in the NDAA (National Defense Authorization Act) that will cut off pathways through which China accesses advanced chips," according to The Economic Times.economictimes.com

The AI Overwatch Act is in the Senate version of the defense bill. If it becomes law, it would bar exports to China of chips more advanced than Nvidia's H200 for a set period, Seoul Economic Daily reported. Lawmakers are also backing the Chip Security Act, which would require tracking where exported chips end up, and the MATCH Act, which would push allies to limit sales of chipmaking equipment to China, Chosun Biz reported. Two aides told Politico that Democrats plan to push for even tougher limits during the lame-duck session.politico.com+2

The allegations

Huang admitted to an affair with Alice Huang, a former executive at Singapore-based Nvidia customer Megaspeed, in an email to staff on November 8. US officials believe she is a spy for China's Ministry of State Security, CNBC reported. Megaspeed has been accused of helping restricted Chinese companies get Nvidia chips. Nvidia's board has opened an independent investigation and says it has no reason to believe trade secrets or US national security were compromised, according to The Herald Business. Three House Republican committee chairs have asked Huang to attend a closed-door briefing on November 18.mbiz.heraldcorp.com+1

A strained truce

Analysts were already rethinking US-China policy after Democrats won control of Congress in the November 3 midterms. The Huang revelations give them more momentum to prioritize national security, Barron's reported. Henrietta Treyz of Veda Partners said tougher controls could be added to the defense bill this year. She also said President Trump "views the company's success as tied to his success." The US-China trade truce expires in early January, and Trump is expected to meet Xi Jinping in mid-November at the APEC summit in Shenzhen.barrons.com

Beijing pushes back

Chinese academics called the push a "witch hunt." Fudan University professor Shen Yi told the state-run Global Times that the accusations follow a "McCarthyist logic," the Spanish news agency EFE reported via Clarín. Chen Hong of East China Normal University accused US lawmakers of using an unresolved controversy as a "political tool." China's Foreign Ministry has said the claims are "groundless speculation," the BBC reported.clarin.com+1
