Nvidia Corp. and Advanced Micro Devices Inc. plan to resume sales of some AI chips in China after securing Washington’s assurances that such shipments would get approved, a dramatic reversal from the Trump administration’s earlier stance on measures designed to limit Beijing’s AI ambitions. US government officials told Nvidia they would green-light export licenses for its H20 artificial intelligence accelerator, the company said in a blog post on Monday — a move that may add billions to Nvidia’s revenue this year, restoring its ability to fulfill orders it had written off as lost due to government restrictions. AMD received similar assurances from the US Commerce Department and plans to restart shipments of its MI308 chips to China once licenses for sales are approved, the company said in a statement Tuesday.
