Cuba exported 85% of goods to the US. - Fidel Castro became president of Cuba in 1959 and established a socialist/communist government, straining relations with the US. - The US imposed an economic embargo on Cuba in 1960 which remains in place today, though some agricultural/medical exports are now permitted.
