Nvidia CEO Jensen Huang is set to hold a media briefing in Beijing on Tuesday, July 16, as part of a high-profile visit to China amid intensifying scrutiny from U.S. lawmakers and rising competition in the AI chip market.

This will be Huang’s second visit to China this year, following an April trip during which he reaffirmed Nvidia’s commitment to the Chinese market—despite ongoing U.S. restrictions on the export of advanced chips.

Since 2022, Washington has tightened curbs on sales of Nvidia’s high-end processors to China, citing national security concerns and the risk of military applications. Most recently, the U.S. imposed a ban on the sale of Nvidia’s H20 AI chips, the most powerful model previously approved for the Chinese market.

Huang’s latest trip has drawn attention on both sides of the Pacific. On Friday, a bipartisan group of U.S. senators sent a letter to the Nvidia chief, urging him to avoid meetings with Chinese entities linked to military or intelligence operations, as well as those on the U.S. restricted export list.

Despite geopolitical tensions, Chinese firms continue to rely heavily on Nvidia’s chips and proprietary CUDA computing platform for AI development. Although local players like Huawei have made strides in GPU development, Nvidia remains a key supplier to China’s tech giants.

In its latest fiscal report, Nvidia revealed that China contributed $17 billion —13% of total revenue— for the year ending January 26. The company recently surpassed a $4 trillion market valuation, underscoring its dominance in the global AI race.

The July 16 press briefing in Beijing is expected to address Nvidia’s vision for the Chinese market, amid delicate geopolitical and business dynamics.
