by OAS on July 26, 1964, but were later rescinded on July 29, 1975. Cuban relations with the OAS have since improved, and the suspension of membership was lifted on June 3, 2009. President John F. Kennedy extended measures by executive order, first widening the scope of the trade restrictions on February 8, 1962 (announced on February 3 and again on March 23, 1962). These measures expanded the embargo to include all imports of products containing Cuban goods, even if the final products had been made or assembled outside Cuba. On August 3, 1962, the Foreign Assistance Act was amended to prohibit aid to any country that provides assistance to Cuba. On September 7, 1962, Kennedy formally expanded the Cuban embargo to include all Cuban trade, except for the non-subsidized sale of food and medicines. Following the Cuban Missile Crisis of October 1962, Kennedy imposed travel restrictions on February 8, 1963, and the Cuban Assets Control Regulations were issued on July 8, 1963, again under the Trading with the Enemy Act, in response to Cuba hosting Soviet nuclear weapons. These measures froze Cuban assets in the U.S. and consolidated existing restrictions. Rapprochement with Cuba The restrictions on U.S. citizens traveling to Cuba lapsed on March 19, 1977; the regulation was renewable every six months, but President Jimmy Carter did not renew it and the regulation on spending U.S. dollars in Cuba was lifted shortly afterwards. President Ronald Reagan reinstated the trade embargo on April 19, 1982, though it was now only restricted to business and tourist travel and did not apply to travel by U.S. government officials, employees of news or film making organizations, persons engaging in professional research, or persons visiting their close relatives. This has been modified subsequently with the present regulation, effective June 30, 2004, being the Cuban Assets Control Regulations, 31 C.F.R. part 515. The current regulation does not prohibit travel by U.S. citizens to Cuba per se, but it makes it illegal for U.S. citizens to have transactions (spend money or receive gifts) in Cuba under most circumstances without a US government Office of Foreign Assets Control issued license. Since even paying unavoidable airfare ticket taxes into a Cuban airport would violate this transaction law, it is effectively impossible for ordinary tourists to visit Cuba without breaking the monetary transaction rule. Increasing legislation The embargo was reinforced in October 1992 by the Cuban Democracy Act
