S. 5643 — Protecting U.S. Investors From Chinese Military Companies Act

This section defines "appropriate committees of Congress" as the Senate Committee on Banking, Housing, and Urban Affairs and the House Committee on Financial Services, and defines "Commission" as the Securities and Exchange Commission.

This section directs the Securities and Exchange Commission to indefinitely suspend trading of securities of any company that remains on the Department of Defense list of Chinese military companies for two annual revisions, within 10 days after the Secretary revises the list. It requires the Commission to notify the appropriate congressional committees when a company is added to the Non-SDN Chinese Military-Industrial Complex Companies List instead of suspending trading, and limits the Commission to promulgating only those regulations and orders strictly necessary to identify securities, administer the trading prohibition, and issue required notices.
