China state media is calling for Nvidia Corp. to prove that its H20 chip is secure, saying it can’t allow flawed chips into the country.China’s top internet watchdog summoned Nvidia representatives earlier this week to discuss what Chinese officials called significant security vulnerabilities in the H20.

China has summoned Nvidia to address alleged H20 chip security flaws, raising fresh concerns about the AI giant’s China business.

In the meeting, Chinese regulators demanded that the U.S. chip company provide explanations on “backdoor safety risks” of its H20 chips to be sold in China and submit relevant materials, the office said.
