NVIDIA CEO Jensen Huang met with U.S. government officials amid escalating concerns over unauthorized Chinese acquisition of AI chips, reflecting high-level diplomatic engagement on export controls.

Nvidia chief executive Jensen Huang is meeting with US officials and lawmakers in Washington this week amid reports that the company's export-controlled processors have been used to train advanced Chinese artificial intelligence models.

According to US outlet Axios, Huang met with US Commerce Secretary Howard Lutnick on Tuesday, citing an anonymous source. Neither the US Commerce Department nor Nvidia confirmed that the meeting took place or disclosed its purpose.

"Jensen is in DC to meet with leaders on both sides of the aisle to discuss Nvidia's work to strengthen the country's supply chain by producing US$500 billion in American technology over four years and American leadership in AI, including leading in open source," an Nvidia spokesperson said.

The visit comes amid a broader investigation into whether restricted Nvidia processors were used to train Moonshot AI models, one of China's most advanced AI systems. US export controls restrict the sale of Nvidia's most advanced processors to China, making such use a potential violation of regulatory requirements.
