Some U.S. companies are attempting to do business on the island - though at least a few have given up that idea, after learning how Cuban leaders treat private enterprise.
Trump also talked of the rejection of the Presidential Directive issued by Obama in October 2016 that recognized the Cuban government as legitimate and equal interlocutor and proposed a civilized relationship created to benefit both peoples.
The new policy also leaves intact most aspects of the Obama Administration's relaxed requirements for travel to Cuba, including the general license authorizing travel for business meetings or professional research.
The embassy reopened for the first time in more than 50 years in July 2015 under the Obama administration, and it was then one of the many changes that took place when the USA, with help from the Vatican, began to reopen diplomatic relations with Cuba.
Trump's policy restricts this form of travel to the island for individuals. No more self-guided tours-but visitors can still bring back rum and cigars.
The Policy directs that the new regulations will prohibit direct financial transactions with entities or sub-entities that are under the control of, or act for or on the behalf of, the Cuban military, intelligence, or security apparatus or personnel thereof. America's relationship with Cuba has been long, complex, and guided for a long time by titanic worldwide geopolitical affairs.
"It is important to continue to promote dialogue and encounter between our neighboring nations and peoples", Bishop Cantu said.
He added that the freedoms of American citizens for travel are also restricted, and opportunities for United States companies and entrepreneurs are reduced in the face of competition, coupled with the loss of income and employment that this would generate.
"I would like to see Cuba and the Cuban people benefit from the economic development and opportunities that we all get, and I am also one who believes that a strong Cuba is good for the rest of the Caribbean", he added.
The embargo against Cuba, which only Congress, not a president, can change, will remain in place, Trump said.
