U.S. Republican presidential candidate Donald Trump says if he is elected, he will reverse all of what he called the "concessions" President Barack Obama made in an effort to normalize relations with Cuba, unless Havana meets certain demands.

"Those demands will include religious and political freedom for the Cuban people and the freeing of political prisoners," Trump said Friday in Miami, home to a large Cuban population.

The real estate billionaire said "We're going to stand with the Cuban people in their fight against communist oppression. We're on the right side. Great people. They are great people. The president's one-sided deal for Cuba and with Cuba, benefits only the Castro regime."

In the past, Trump has said he supports normalized relations, but would have preferred a better deal.
