Nvidia CEO Jensen Huang will attend the opening ceremony of China's international supply chain expo in Beijing on Wednesday, according to state media, as the US tech giant strains under Washington's curbs on AI chips.

The California-based firm produces some of the world's most advanced semiconductors but has been unable to sell certain artificial-intelligence chips to China because Washington has tightened export restrictions on the critical technology.

But Nvidia said on Tuesday it will resume sales of its H20 artificial intelligence chips to China, after exports were halted due to US licensing curbs.

"Nvidia is filing applications to sell the Nvidia H20 GPU again," it said.

"The US government has assured Nvidia that licenses will be granted, and Nvidia hopes to start deliveries soon.

President Xi Jinping has called for China to become more self-reliant as uncertainty in the external environment increases.

Broadcaster CCTV said on Tuesday that Huang "will be present at the opening ceremony of the 3rd China International Supply Chain Expo on July 16 and participate in related activities".

The report cited the China Council for the Promotion of International Trade, an official body controlled by the Commerce Ministry.

It will be Huang's third trip to China this year, according to CCTV. Huang told Vice Premier He Lifeng on a visit to Beijing in April that he "looked favourably upon the potential of the Chinese economy", according to Xinhua News Agency.

Huang, an electrical engineer, said he was "willing to continue to plough deeply into the Chinese market and play a positive role in promoting US-China trade cooperation", Xinhua reported. (AFP)
