A United States embargo has prevented 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 condemnation for its adverse impact on Cubans, including by the United Nations who have formally condemned it intermittently since 1992.
