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, however, 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. President Trump unveiled a new policy toward Cuba in 2017 introducing new sanctions and partially rolling back some of the Obama Administration's efforts to normalize relations. On March 4, 2019, the Administration ratcheted up its economic pressure on Cuba by allowing some lawsuits to go forward against over 200 Cuba entities operated by the Cuban military, intelligence, or security services for trafficking in confiscated property."
