This is the second time that Nvidia’s permission to sell in China has changed. As widely reported in April, the firm got re-approved to sell chips to China after a dinner meeting between Huang and Trump in the spring, apparently including a tit-for-tat deal in which Nvidia would create new server setups stateside.

The head of Nvidia downplayed his role in getting the U.S. government to lift a ban on selling an advanced computer chip in China and said it will take time to ramp up production once orders for the AI-processor come in.

CEO Jensen Huang said the company will boost supply of China-compliant H20 chips in the coming months and look to bring more advanced semiconductors.
