In a significant escalation of export controls, the US Commerce Department has added 140 Chinese technology firms, including key chipmaking equipment manufacturers, to its entity list. This move aims to disrupt China's military technological advancements and AI capabilities by limiting access to crucial semiconductor technology. China condemned the restrictions as economic coercion, while US officials assert these actions are necessary for national security. The US also implements stringent measures on high-bandwidth memory chips and extends controls to foreign manufacturers using American technology, as China ramps up its own semiconductor self-sufficiency efforts.
