The United Nations Secretary General has warned that there could be a humanitarian collapse in Cuba.  A warning coming amid U.S. threats to tariff any country that supplied oil to the Caribbean island nation. President Donald Trump signed an Executive Order on January 29th in which he determined that the policies, practices and actions of the Cuban Government constituted a unusual and extraordinary threat to the national security and foreign policy of the United States.  The order threatens to add an additional levy on countries that provide oil to Cuba while the United Nations urged dialogue.
