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”.

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.

NVIDIA has been called in by Chinese regulators over claims that its H20 AI chip poses security risks, putting billions in potential sales at stake.
