US Treasury moves to curb AI, chip and biotech deals in China and Russia

The US Treasury proposed new regulations expanding restrictions on American investments in sensitive technologies like AI, chips, and biotech in countries including China, Russia, and North Korea to protect national security. The draft rule broadens the list of targeted sectors and countries, replacing 'AI systems' with 'super intelligence systems' and tightening investment bans. Public comments are open until December 7 before final rules are set.
