China has banned U.S. chip maker Micron from selling its products to Chinese companies working on key infrastructure projects, citing national security risks. The development comes nearly two months after the country’s cybersecurity authority initiated a probe in late March 2023 to assess potential network security risks. “The purpose of this network security review of Micron’s products is to prevent product network security problems from endangering the security of national critical information infrastructure, which is a necessary measure to maintain national security,” the Cyberspace Administration of China (CAC) said.
