US political pressure mounts to cut off Cuba's oil supply through tariffs and sanctions

The US government is taking coordinated action to restrict Cuba's access to oil, with President Trump declaring a national emergency and signing an order allowing tariffs on countries that supply oil to Cuba, while Republican lawmakers simultaneously propose new sanctions legislation with similar aims. Both executive and legislative branches are pushing measures that would impose tariffs on any country supplying petroleum to the island nation. This represents a unified US political effort to create an oil shortage in Cuba through economic pressure on its suppliers.
