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 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. [...] President Trump unveiled a new policy toward Cuba in 2017, introducing new sanctions and rolling back some of the Obama Administration's efforts to normalize relations. By 2019, the Trump Administration had largely abandoned the previous Administration's policy of engagement by increasing economic sanctions significantly to pressure the Cuban government on its human rights record and its support for the regime of Nicolás Maduro in Venezuela."
