The United States embargo against Cuba is an embargo preventing U.S. businesses and citizens from conducting trade or commerce with Cuban interests since 1960. Modern diplomatic relations are cold, stemming from historic conflict and divergent political ideologies. U.S. economic sanctions against Cuba are comprehensive and impact all sectors of the Cuban economy. It is the most enduring trade embargo in modern history. The U.S. government influences extraterritorial trade with Cuba. The embargo has faced international criticism for its adverse impact on Cubans, including by the United Nations who have formally condemned it intermittently since 1992.
The U.S. government first launched an arms embargo against Cuba in 1958, with their energy and agricultural sectors targeted in 1960. The Cuban Revolution led to nationalization and a trade war with the U.S. that prompted seizure of American economic assets, including oil refineries. The U.S. retaliated with a total embargo on Cuban trade, with exceptions for food and medicine. Cuba held nuclear missiles for the Soviet Union during the 1962 Cuban Missile Crisis, which resulted in the U.S. fully blockading the island. The embargo was loosened during the Cuban thaw from 2015 to 2017, tightening sharply thereafter over human rights in Cuba.
