A day after the U.S. government opened an investigation into whether Nvidia, America’s leading chipmaker, violated rules with its sales to China, its chief executive, Jensen Huang, met with Chinese trade officials in Beijing.

Mr. Huang had been invited to meet with the China Council for the Promotion of International Trade, a state-backed trade body, according to state media.

The visit was covered by Chinese state media, which reported that Mr. Huang said U.S. controls on Nvidia’s sales to China had a significant impact on the company’s business. Nvidia, the report said, would “continue to spare no effort” to make products that comply with regulations and “unswervingly serve the Chinese market.”

Mr. Huang headed to Beijing during a week when his company’s relationship with Washington has fluctuated dramatically.

On Monday, Nvidia promised to invest $500 billion in artificial intelligence infrastructure in the United States, winning praise from President Trump’s administration, which called the investment “the Trump Effect in action.”

The next day, the company disclosed that U.S. officials said it would need a license for any sales to China. The new requirement would force Nvidia to take a $5.5 billion hit on inventory it had already planned to sell in China.
