China Warns US on Chip Curbs as Spy-Linked Firm Got Banned Nvidia Chips

China warned the US against tightening chip export controls as a company linked to a suspected spy reportedly obtained banned Nvidia AI chips, escalating tensions ahead of a planned Trump-Xi meeting. Shanghai Longteng Intelligent Computing, founded by Alice Huang, acquired servers with Nvidia's H800 chips, which Washington banned for export to China in 2023, according to Bloomberg. The servers were bought from Dell by Aperia Cloud Services, an Nvidia partner in Singapore, though the acquisition method remains unclear. US lawmakers are pushing for stricter limits on chip sales to Beijing, with House Speaker Mike Johnson citing a "developing consensus in Congress." Beijing denies Huang is a spy, calling allegations a pretext for a "technological blockade," while Megaspeed investigates compliance and Malaysia probes a subsidiary.
