Nvidia CEO Jensen Huang expressed disappointment over reports that China has banned purchases of the company’s AI RTX Pro 6000D chips, affecting major firms like ByteDance and Alibaba.

Huang described Nvidia’s China business as “a rollercoaster” and noted that U.S.-China geopolitical tensions and previous export restrictions have complicated operations.

Despite setbacks—including a recent Chinese anti-monopoly probe—Huang emphasized the importance of the Chinese AI market and pledged continued support for both Chinese companies and the U.S. government, CNBC has reported.

Meanwhile, Nvidia announced a $15 billion investment in U.K. AI infrastructure during President Trump’s state visit.
