The Treasury Department on Thursday proposed a rule to curb American high-tech investments, including those in artificial intelligence, that flow outbound to U.S. adversaries, according to a report in The Hill. The summary of that report names China, Russia and North Korea among the adversaries the proposal would reach, along with what it calls other "countries of concern."

The rule would expand restrictions already in place under the Outbound Investment Security Program, known as OISP. According to The Hill, the expansion covers hypersonic systems and quantum information technologies, as well as high-performance computing and supercomputing. The summary gives that list of fields without describing how the restrictions would work, and it stops there, so it is not clear whether the proposal reaches other technology sectors.

The Hill's report was written by Ryan Mancini. Its summary describes the action as a proposed rule rather than a final one, and it does not say how long the department would take to finalize the measure. The summary also does not include the rule's text, a public comment period, or any explanation from Treasury officials for the proposal.

Because only one report was available for this account, the details here rest on The Hill's summary alone. Where that summary is incomplete, this account leaves the gap open rather than filling it with outside information.
