The Office of Foreign Assets
Control ("OFAC") of the US Department of the Treasury
administers and enforces economic and trade sanctions based on
US foreign policy and national security goals against targeted
foreign countries, terrorists, international narcotics
traffickers, and those engaged in activities related to the
proliferation of weapons of mass destruction. OFAC acts under
Presidential wartime and national emergency powers, as well as
authority granted by specific legislation, to impose controls on
transactions and freeze foreign assets under US jurisdiction.
