These rules, effective Wednesday, aim to safeguard national security and technological capabilities amidst escalating US competition. While designed to enhance outward investment quality, they could complicate global expansion for Chinese firms and access to Chinese capital for foreign partners, raising concerns about technology transfers and broader geopolitical implications.
