China’s cyber regulator on Thursday said it had held a meeting with Nvidia over what it called “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”.

Chinese authorities summoned Nvidia Corp. to discuss alleged security risks related to its H20 chips, casting doubt over the domestic business of the world’s most valuable company weeks after co-founder Jensen Huang met senior officials in Beijing.

Nvidia must produce "convincing security proofs" to eliminate Chinese users' worries over security risks in its chips and regain market trust, a commentary published by China's state-run media People's Daily said on Friday.
