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. [...] 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 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. It took actions to allow lawsuits against those trafficking in property confiscated by the Cuban government and tightened restrictions on travel to Cuba, including terminating cruise ship travel from the United States and U.S. flights to Cuban cities other than Havana."
