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.

The Chinese government fears that H20 GPUs pose a spying risk, but Nvidia says its products do not have backdoors.

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