U.S. President Donald Trump has signed an executive order declaring a national emergency, according to Jin10. The order establishes a procedure to impose tariffs on goods from countries that sell or otherwise provide oil to Cuba. This move is part of a broader strategy to exert economic pressure on Cuba by targeting its oil supply chain. The White House aims to discourage international trade with Cuba, particularly in the energy sector, as part of its foreign policy objectives. The executive order reflects ongoing tensions between the United States and Cuba, with the U.S. government seeking to limit Cuba's access to resources and influence its economic activities.
