According to reports, Trump enforced restrictions on former President Barack Obama's lenient travel policy to the country. These measures are a sop to hard-line dead-enders that loathe diplomatic engagement and never wanted an opening to Cuba at all, and by caving once again to foreign policy hard-liners Trump has shown his own weakness and poor judgment.
There are significant worries within the Cuban regime that an end of Venezuelan support will mean a return of the "special period" of the 1990s, when the end of Soviet support led to widespread hunger and economic collapse.
Donald Trump's decision to roll back Obama era warming relations with Cuba and to tighten some restrictions has been denounced by the Russian government and described the policy as resorting to Cold War-era rhetoric.
"It is doubtful that they will trigger any move in Cuba towards a new governing structure or new leadership", said Shifter.
But the reforms have been slow and Cuba is in recession, dragged down by the decline in cut-price oil imports from its crisis-hit ally Venezuela. In fact, Trump's policy even keeps the American embassy in Havana open.
Restrictions on American agricultural and telecommunications equipment to Cuba were eased, and it became much easier for Americans to travel to Cuba as regular air travel between the countries was restored.
While these moves in themselves are likely to have little significant effect on the ruling layer of the Cuban government, they will negatively impact the increasing numbers of Cubans who are reliant on U.S. tourism, from the owners of Airbnbs to restaurant workers and owners to taxi drivers and hotel workers, among others.
Rep. Tom Emmer, R-Minn., said Trump's new Cuba policy "will hurt the United States economically, making it harder for our nation's farmers to access new markets and cutting the knees out from under our travel and manufacturing industries".
"GAESA has taken full advantage of the new US engagement".
Q: What did Trump say about it? In the weeks after his election victory, Trump forcefully hinted at his plans for Cuba.
Mr. Emmer, one of Mr. Trump's biggest supporters on Capitol Hill, picked up on Crawford's criticism, saying the new directive could violate his promise to provide security in the United States. People-to-people travel, too, allows a lot of room for personal travel to Cuba to see family and establish stronger connections. This is likely to affect pending hotel projects with Cuban companies that have ties to the military. The ability of Americans to travel freely on vacation to the country will be scrapped.
Q: What remains in place from Obama's policy?
Trump's vow to keep the broader decades-old USA economic embargo on Cuba firmly in place drew criticism from some US farmers, especially growers of corn, soybeans and rice.
Q: What's been the response to Trump's efforts?
"You have not betrayed us".
The Castro dictatorship changed from Fidel to Raul, but that's only a matter of stationery, not policy and improvements for the Cuban people.
The President's decision last week was not without controversy in the United States.
One of the central reasons cited in Mr. Trump's change in US-Cuba policy has to do with human rights, with the president announcing in Miami on Friday that he would "expose the crimes of the Castro regime and stand with the Cuban people in their struggle for freedom".
The foreign ministry said any USA strategy aimed at applying pressure to bring about change to Cuba's political, economic and social system would fail.
