United States President Donald Trump has signed an executive order to impose new tariffs on any country that supplies oil to⁠ Cuba, the latest move in Washington’s campaign of pressure on Havana. The order, signed by Trump on Thursday, describes the Cuban government as an “unusual and extraordinary threat” to US national security. The US has since taken effective control of Venezuela’s oil sector, and Trump has promised to stop oil shipments previously sent to Cuba. Just this week, Trump said that “Cuba will be failing pretty soon”, noting the lack of Venezuelan oil or revenue arriving in Havana. According to The Financial Times, Mexico supplied some 44 percent of Cuba’s oil imports, and Venezuela supplied 33 percent until last month.
