Nvidia CEO Jensen Huang criticized U.S. export controls blocking the sale of its AI chips to China. Last month, the chipmaker noted a $5.5 billion write-down to its inventory, after the U.S. demanded companies get a license to sell their AI chips to China.

Nvidia CEO Jensen Huang reportedly called Washington’s export curbs on the sale of AI chips to China a “failure” that would drive Chinese rivals to speed up developing their own semiconductors.

The now-scrapped rule would have limited the number of advanced artificial intelligence chips NVIDIA could sell to certain countries.
