The U.S. Treasury Department has issued a final rule–and created a new division to oversee it–that will attempt to limit outbound investments to China related to sensitive technologies with military applications.

The rule, set to take effect January 2, 2025, and be overseen by the Treasury’s brand-new Office of Global Transactions, would prohibit U.S. companies from outbound investment to China, Hong Kong, and Macau in three key technologies: semiconductors and microelectronics; quantum information technologies; and artificial intelligence.

“Artificial intelligence, semiconductors, and quantum technologies are fundamental to the development of the next generation of military, surveillance, intelligence, and certain cybersecurity applications like cutting-edge code-breaking computer systems or next generation fighter jets,” said Paul Rosen, assistant secretary for investment security, in a press release Monday. “U.S. investments, including the intangible benefits like managerial assistance and access to investment and talent networks that often accompany such capital flows, must not be used to help countries of concern develop their military, intelligence, and cyber capabilities.”
