Answer:
The United States imposed an embargo on Cuba since 1960.
Step-by-step explanation:
The commercial, economic and financial embargo of the United States against Cuba was imposed in October 1960, in response to the expropriations by the new revolutionary government of properties of American citizens and companies in the island after the Cuban Revolution. Although initially it excluded food and medicines, in February of 1962 the United States hardened the measures and the blockade almost became total.
