American chipmaking giant Nvidia (NVDA) says it plans to resume sales to China of an artificial intelligence chip that’s become part of a global race pitting the world’s biggest economies against each other.

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.

Washington has been concerned China could use Nvidia’s chips to get a jump on the U.S. in high-tech fields, particularly when it comes to artificial intelligence.
