The Trump administration is imposing new sanctions on Cuba this week including banning all U.S. travel to the island for tourism in response to the Cuban governments support of Venezuelan leader Nicolas Maduro .

The U.S. Department of the Treasury announced that the changes will go into effect on Wednesday, June 5. Those who have already purchased flight tickets or made other travel reservations will not be affected.

This Administration has made a strategic decision to reverse the loosening of sanctions and other restrictions on the Cuban regime, Treasury Secretary Steven Mnuchin said in a statement. These actions will help to keep U.S. dollars out of the hands of Cuban military, intelligence, and security services.
