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.

China's cyberspace regulators have summoned Nvidia over security concerns about its H20 chips. They claim the chips can be tracked and turned off remotely.

Nvidia said on Thursday its products have no "backdoors" that would allow remote access or control after China raised concerns over potential security risks in the firm's H20 artificial intelligence chip.
