By Banning U.S. Chipmaker Micron, China Hits Back at Western Tech Restrictions

China’s ban on the U.S. chipmaker Micron signals Beijing’s willingness to use more aggressive legal tools against Western technology companies in response to the United States and its allies’ expanding export restrictions, which will only further compel foreign firms in the sector to reduce their exposure and sales to China. Following an investigation that appears to have lasted less than two months, the Cyberspace Administration of China (CAC) announced on May 21 that it would ban China’s critical infrastructure operators from using chips produced by U.S. semiconductor manufacturer Micron.
