The U.S. Treasury has proposed a rule to expand the authority of the Committee on Foreign Investment in the United States (CFIUS) to review foreign real estate purchases near American military bases, adding 56 facilities across 30 states. This move, driven by national security concerns, marks the largest expansion of CFIUS' jurisdiction since the 2018 legislation. Concerns about espionage have led to increased scrutiny of foreign property acquisitions near sensitive military installations, with the new rule extending CFIUS' oversight to land deals within specific distances of additional military sites.
