The U.S. will launch a major semiconductor crackdown targeting 140 Chinese companies, including Naura Technology, Piotech, and SiCarrier Technology, to hinder Beijing’s chipmaking and AI military ambitions. Restrictions include advanced memory chips, 24 chipmaking tools, and the expanded foreign direct product rule. The move intensifies U.S.-China tech tensions, impacting firms like Huawei-linked suppliers and global chipmakers like Samsung and Micron.
