China Demands US Drop Tech Export Curbs After Nvidia Warning

The Chinese government called on Washington to repeal its technology export curbs after California-based chip designer Nvidia said a new product might be delayed and some work might be moved out of China.

The latest controls add to mounting U.S.-Chinese tension over technology and security. American officials say they need to limit the spread of technology that can be used to make weapons.

Nvidia said it was told last week it needs a U.S. government license to export any product with performance equal to its A100 graphics processing chips or better to China, Hong Kong or Russia. It said buyers of the A100, and development of the newer H100, might be affected.

But in an amended disclosure Thursday to U.S. securities regulators, the company said the U.S. government was offering some reprieve by authorizing certain chip exports that will enable Nvidia to keep supplying them to American customers through March.
