The White House says the 15% fee on U.S. chip sales to China, agreed to by Nvidia and AMD in exchange for export licenses, could be expanded to other semiconductor makers. The arrangement allows for sales of models like Nvidia’s H20, which meets U.S. export restrictions but outperforms China’s domestic chips. However, Chinese authorities have reportedly questioned tech giants including Tencent and ByteDance on why they’re buying U.S. chips instead of homegrown alternatives.
