China’s cyber regulator on Thursday said it had called in Nvidia for a meeting over alleged “serious security issues” with the company’s artificial intelligence chips. It said US AI experts had “revealed that Nvidia’s computing chips have location tracking and can remotely shut down the technology”.

China raised concerns over potential security risks in Nvidia's H20 artificial intelligence chip, casting uncertainty over the U.S. company's sales prospects in China weeks after a U.S. export ban was reversed.

Nvidia earlier this month said the U.S. government is giving permission to sell its H20 microchip again in China — but now a Chinese regulator is raising a red flag.
