Nvidia plans to resume sales of its H20 AI chip to China after securing Washington’s assurances that such shipments would get approved, a dramatic reversal from the Trump administration’s earlier stance.

US government officials told Nvidia they would green-light export licenses for the H20 artificial intelligence accelerator, the company said in a blog post. That China-specific variant was created to comply with earlier trade curbs, but has since April also been blocked from sale in the country without a US permit. Billionaire co-founder Jensen Huang appeared on Chinese state broadcaster CCTV shortly after Nvidia announced the decision, saying the company had secured approval to begin shipping.

The US move comes after weeks of thawing relations between Washington and Beijing, guided by an opaque truce that’s designed to see both sides approve exports of crucial technologies. The US wants China to allow more sales of essential rare-earth minerals, and in exchange is lifting a spate of recent export controls that were imposed in the lead-up to last month’s trade talks in London. Throughout those talks, President Donald Trump’s team insisted that controls on Nvidia’s H20 chips were not up for discussion.
