But it also reiterated "its willingness to continue the respectful dialogue and cooperation".
Cheered by Cuba hardliners in both parties, Trump's new policy is broadly opposed by USA businesses eager to invest in Cuba.
Trump, taking a tougher approach against Havana after promising to do so during the presidential campaign, will outline stricter enforcement of a long-time ban on Americans going to Cuba as tourists and will seek to prevent US dollars from being used to fund what the new USA administration sees as a repressive military-dominated government.
"Travel brings income to the people who work in our industry; President Trump's statements indicate that the Cuban people, rather than the government will be hit by this policy change", he added.
In 2015, Department of Tourism Commissioner Beverly Nicholson-Doty said it would be "totally unrealistic not to acknowledge and plan for the inevitable risks associated with a new, large competitor in the region".
By restricting individual U.S.travel to Cuba, the new policy also risks cutting off a major source of income for Cuba's private business sector, which the policy is meant to support.
The Cuban government rebuked those statements in a lengthy response Friday, writing that Trump's executive order betrays a double standard on human rights. "Our new policy begins with strictly enforcing US law".
But he did tighten rules for Americans traveling to Cuba, ban ties with a military-run tourism firm and reaffirm the existing USA trade embargo - which will be firmly enforced. "The United States will always react to what the Cuban government did".
1962: Castro agrees to allow the Soviet Union to deploy nuclear missiles on the island bringing the United States and the USSR to the brink of nuclear war. Still, it will be the latest attempt by Trump to overturn parts of Obama's presidential legacy.
"You could say, 'You could buy a drink anywhere, ' but we want to come to a famous, very nice place", said Russell Francis, 35, a special education teach from Houston, after visiting Sloppy Joe's, which won renown during the 1920s U.S. Prohibition era when American tourists flocked to Havana to drink and gamble to their heart's content.
Earlier today, President Trump announced upcoming revisions to the Cuban embargo.
Trump had framed his revision as a move against a "cruel and brutal" regime: bypassing the state military-run business group GAESA to channel investment to the people. The effect of this new policy will be strengthening the revolutionary leadership and seeing that it's right.
As a result, the changes - though far-reaching - appear to be less sweeping than many U.S.pro-engagement advocates had feared. The revised regulations will no longer authorize individual people-to-people travel. And Cuban-Americans will be able to continue to visit their family in Cuba and send them remittances, according to a fact sheet.
"Our new policy begins with strictly enforcing USA law", he told a cheering crowd in Miami's Little Havana, the spiritual home of the Cuban- American community.
The policy also allows Americans to continue patronizing state-run hotels and other businesses that are not directly linked with Cuba's military and state-security services.
