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.

This is the second time that Nvidia’s permission to sell in China has changed. As widely reported in April, the firm got re-approved to sell chips to China after a dinner meeting between Huang and Trump in the spring, apparently including a tit-for-tat deal in which Nvidia would create new server setups stateside.
