President Joe Biden has signed an executive order aimed at blocking and regulating high-tech U.S. investments in China. Focused on national security goals rather than economic interests, the order covers advanced computer chips, microelectronics, quantum information technologies, and artificial intelligence. The move is seen in the context of the intensifying competition between the U.S. and China. The order seeks to limit China’s use of U.S. investments in its technology companies for military advancements while maintaining broader trade relations. The administration consulted with allies and industry in shaping the executive order, aiming to prevent disruption to China’s economy while addressing national security concerns.
