The Foreign Assets Control Regulations, administered by the Treasury Department, block the assets here of Communist China, North Korea and their nationals and prohibit unlicensed dealings involving property in which Communist China, or North Korea, or their nationals, have any interest. The regulations prevent the use of United States financial facilities by those countries and their nationals. These regulations also prohibit the unlicensed importation of goods of Chinese Communist or North Korean origin. Treasury regulations also prohibit Americans, including foreign subsidiaries of United States firms, from participating in the purchase or sale of certain important commodities for ultimate shipment from any country outside the United States to the countries of the Soviet bloc. These transactions controls, which are complementary to the United States export control laws, are administered by the Treasury Department under Foreign Assets Control Regulations. _APPENDIX B_ =Statistical Tables= Table 1.
