On June 21, 2000, the President issued Executive Order 
                13159 (the ``order'') blocking property and interests 
                in property of the Government of the Russian Federation 
                that are in the United States, that hereafter come 
                within the United States, or that are or hereafter come 
                within the possession or control of United States 
                persons that are directly related to the implementation 
                of the Agreement Between the Government of the United 
                States of America and the Government of the Russian 
                Federation Concerning the Disposition of Highly 
                Enriched Uranium Extracted from Nuclear Weapons, dated 
                February 18, 1993, and related contracts and agreements 
                (collectively, the ``HEU Agreements''). The HEU 
                Agreements allow for the downblending of highly 
                enriched uranium derived from nuclear weapons to low 
                enriched uranium for peaceful commercial purposes. The 
                order invoked the authority, inter alia, of the 
                International Emergency Economic Powers Act (50 U.S.C. 
                1701 et seq.) and declared a national emergency to deal 
                with the unusual and extraordinary threat to the 
                national security and foreign policy of the United 
                States posed by the risk of nuclear proliferation 
                created by the accumulation of a large volume of 
                weapons-usable fissile material in the territory of the 
                Russian Federation.
