President Joe Biden’s administration says it is finalizing rules to curb investment in AI and other tech sectors in China, Reuters reports.

The rules, which were first proposed in June by the U.S. Treasury and imposed by an executive order signed by President Biden in August 2023, cover certain AI systems, quantum information systems, as well as semiconductors and microelectronics. Specifically, the rules address technologies critical to military and surveillance systems, such as computer decryption systems and next-generation fighter jets.

Starting January 2, investors will be prohibited from channeling capital and “intangible benefits,” such as managerial assistance and access to investment and talent networks, to help China and other “countries of concern” to develop their military, intelligence and cybersecurity capabilities.

Overseen by the Treasury’s new Office of Global Transactions, the new rules contain an exclusion allowing U.S. investments in publicly traded securities. But previous decrees prohibit the purchase and sale of securities of certain “designated” Chinese companies.
