China’s commerce ministry objected Saturday to a proposed U.S. Treasury rule widening limits on American investment in sensitive technologies. It called the proposal discriminatory and said it reflected an overly broad invocation of national security, warning it could harm bilateral economic and trade cooperation and U.S. business interests. The ministry said it would monitor developments and reserved the right to take corresponding measures.

Announced Thursday, the proposal would broaden the Outbound Investment Security Program. It adds biotechnology and covers areas including hypersonic systems, high-performance computing, supercomputing, artificial intelligence and quantum information technologies. Some covered investments would be prohibited, while others would require notification. Treasury said the rule is intended to prevent adversaries from using U.S. investment to develop technologies that threaten U.S. national security. Treasury is accepting public comments through Dec. 7 before issuing a final rule.
