US Treasury proposes barring new US private investment in Chinese brain-computer interface companies

The US Treasury proposed rules on 22 October 2026 that would prohibit US persons from most new non-public investments in companies that develop or produce brain-computer interfaces and are based in, or owned or controlled from, China, Hong Kong or Macau. The definition covers invasive and non-invasive systems and their software. Brain-computer interfaces sit in the rule's prohibited tier, with no notify-only option, no technical threshold and no small-deal exemption for direct investments. Comments are due by 7 December 2026.
