From the Document: "Since the early 1960s, when the United States imposed a trade embargo on Cuba, the centerpiece of U.S. policy toward Cuba has consisted of economic sanctions aimed at isolating the government. In December 2014, the Obama Administration initiated a major policy shift moving away from sanctions toward engagement and the normalization of relations. The policy change included the rescission of Cuba's designation as a state sponsor of international terrorism in May 2015; the restoration of diplomatic relations in July 2015; and efforts to increase travel, commerce, and the flow of information to Cuba by easing restrictions on travel, remittances, trade, telecommunications, and banking and financial services (accomplished through amendments in 2015 and 2016 to the Cuban Assets Control Regulations [CACR], administered by the Department of the Treasury, and the Export Administration Regulations [EAR], administered by the Commerce Department)."
