U.S. Treasury Secretary John Snow says Washington is cracking down on ten companies which are controlled by the Cuban Government or Cuban nationals.
The United States has embargoed most trade with Cuba for the past four decades in the hope that economic pressure would help topple the communist government led by Fidel Castro.
The U.S. Treasury Secretary used a speech Monday to announce government action against nine travel agencies and a gift forwarding company based in Cuba and several other nations. Washington is putting these companies on a list that makes it illegal for Americans to do business with them.
He delivered the speech to a group of Cuban-American business executives in the southern U.S. state of Florida. Cuban-Americans play an influential role in Florida politics, a key state in presidential elections.
