China's Cyberspace Administration (CAC) summoned Nvidia on July 31, 2025, to answer questions about potential backdoor security risks in the H20 AI chip, including tracking and remote shutdown capabilities. This follows a U.S. reversal of an April export ban. Nvidia has reportedly ordered 300,000 H20 chips from TSMC amid surging Chinese demand. The company also faces an antitrust probe in China stemming from its acquisition of Mellanox.
