US Treasury proposes tighter China investment rules for AI and chips

The US Treasury on Oct. 22 proposed restricting American investment in sensitive technologies in China, Russia, Iran and North Korea, covering advanced chips, AI, quantum computing, hypersonics and biotech. The rules would ban some deals and require reporting for others above $50,000, with public comments open before final regulations.

• Covers advanced chips, AI, quantum, hypersonics and biotechnology
• Reporting threshold set at investments above $50,000; stock purchases excluded
• Implements the COINS Act passed by Congress in 2025
• China called the restrictions discriminatory and vowed countermeasures
