United States: OFAC Issues Chinese Military-Industrial Complex Sanctions Regulations

On 16 February 2022, the US Department of the Treasury's Office of Foreign Assets Control (OFAC) published a final rule adding formal regulations to implement previously announced sanctions regarding Chinese Military-Industrial Complex companies.
These formal regulations are the result of Executive Order (EO) 13959 dated 12 November 2020, which prohibited U.S. persons from engaging in transactions in publicly traded securities or derivatives or similar securities of any Chinese company designated by the U.S. government as an enabler for Chinese military objectives.
EO 14032 issued by President Biden, which is currently in effect, prohibits the purchase or sale of any publicly traded security of any person listed in the attachments to the executive order and any transaction that circumvents or avoids or attempts to violate any of the prohibitions set forth in the order.
