The Chinese authorities on July 31 summoned Nvidia over alleged “serious security issues” in the company’s artificial intelligence chips, according to the regime’s cyberspace regulator.

In an online statement, the Cyberspace Administration of China (CAC) said it had requested Nvidia to explain the “security risks linked to back doors” in the company’s H20 chips sold in China and to provide supporting materials.
