This bill aims to enhance national security by restricting foreign influence on U.S. military installations. It prohibits the Secretary of Defense from renewing, extending, or entering into new long-term concessions agreements with retailers controlled by a covered nation , as defined in existing law, to operate on military installations. This prohibition applies unless the Secretary issues a waiver or the Committee on Foreign Investment in the United States (CFIUS) determines there is no national security detriment. For existing agreements, the Secretary must review all long-term concessions with retailers operating on military installations within 180 days of the bill's enactment to identify those controlled by a covered nation. If such control is determined, the agreement must be terminated within 30 days. Similar to new contracts, termination can be waived by the Secretary or if CFIUS finds no national security risk. The Secretary can waive these prohibitions or termination requirements if the retailer provides goods or services vital for military welfare and morale, no reasonable alternatives exist, and adequate national security risk mitigation measures are in place. CFIUS plays a crucial role, requiring covered retailers to disclose relationships with covered nations and conducting investigations into their national security implications. Retailers receiving a favorable CFIUS determination must provide annual updates on ownership changes, and agreements can be terminated for non-compliance or misrepresentation of ownership.
