Cuba Sanctions: Legislative Restrictions Limiting the Normalization of Relations [February 3, 2017] [open pdf - 607KB]
"U.S. economic sanctions on Cuba date back to the early 1960s when the Cuban government under Fidel Castro began to build a repressive communist dictatorship and aligned with the Soviet Union. The trade embargo was first imposed in 1962 under the authority of the Foreign Assistance Act of 1961 and the Trading with the Enemy Act and soon broadened to include a prohibition on most financial transactions with Cuba. In 1963, the Treasury Department issued the Cuban Assets Control Regulations (CACR); they remain the main body of embargo regulations today, and have been amended many times over the years to reflect changes in policy. In addition, since Cuba is an embargoed country, all exports to Cuba must be authorized by the Department of Commerce as implemented through the Export Administration Regulations (EAR). [...] This report provides information on legislative provisions restricting relations with Cuba. It lists the various provisions of law comprising economic sanctions on Cuba, including key laws that are the statutory basis of the embargo, and provides information on the authority to lift or waive the restrictions."
