U.S. Clears Nvidia to Resume AI Chip Sales to China. The U.S. government has approved Nvidia to restart sales of its advanced AI chips to China, easing a key restriction in the global tech rivalry between Washington and Beijing.. The green light applies to Nvidia's H200 processor — its second-most powerful AI chip — which had previously been blocked over fears it could strengthen China's tech sector and military. U.S. officials say shipments will be allowed as long as there is enough domestic supply and Chinese buyers meet strict security requirements, including bans on military use. President Donald Trump had signaled the shift last month, saying sales would be limited to approved customers and subject to a 25% fee paid to the U.S. government. Nvidia welcomed the move, saying it would support U.S. manufacturing and jobs. China, meanwhile, criticized what it calls the politicization of technology trade. The most advanced Blackwell chip remains banned, keeping pressure on China to develop its own alternatives as the AI race accelerates.
