Title: History of Cuba
Content:  The United States severed diplomatic relations with Cuba on 3 January 1961, and further restricted trade in February 1962. The Organization of American States, under pressure from the United States, suspended Cuba's membership in the body on 22 January 1962, and the U.S. government banned all U.S.–Cuban trade on 7 February. The Kennedy administration extended this ban on 8 February 1963, forbidding U.S. citizens to travel to Cuba or to conduct financial or commercial transactions with the country. At first the embargo did not extend to other countries, and Cuba traded with most European, Asian and Latin American countries and especially with Canada. However, the United States later pressured other nations and American companies with foreign subsidiaries to restrict trade with Cuba. The Helms–Burton Act of 1996 makes it very difficult for foreign companies doing business with Cuba to also do business in the United States, forcing them to choose between the two marketplaces.
Title: United States embargo against Cuba
Content:  The United States embargo against Cuba prevents American businesses, and businesses organized under US law or majority-owned by citizens of the United States, from conducting trade with Cuban interests. It is the most enduring trade embargo in modern history. The US first imposed an embargo on the sale of arms to Cuba on March 14, 1958, during the Fulgencio Batista regime. Again on October 19, 1960, almost two years after the Cuban Revolution had led to the deposition of the Batista regime, the US placed an embargo on exports to Cuba except for food and medicine after Cuba nationalized the US-owned Cuban oil refineries without compensation. On February 7, 1962, the embargo was extended to

In 1962, President Kennedy broadened the partial trade restrictions imposed after the revolution by Eisenhower to a ban on all trade with Cuba, except for non-subsidized sale of foods and medicines. A year later travel and financial transactions by U.S. citizens with Cuba was prohibited. The United States embargo against Cuba was to continue in varying forms. Despite tensions between the United States and Cuba during the Kennedy years, relations began to thaw somewhat after the Cuban Missile Crisis.

Between 1954 and 1959, trade between Cuba and the United States was at a higher level than what it was in 2003, according to a BA dissertation submitted to the Teresa Lozano Long Institute of Latin American Studies, with 65% of Cuba's total exports sent to the United States while American imports totaled 74% percent of Cuba's international purchases. After the formal implementation of the embargo and the passage of Proclamation 3355, there was a 95% decrease in Cuba's sugar quota, which canceled roughly 700,000 tons of the 3,119,655 tons previously allotted to the United States. A year later, Cuba's sugar quota was reduced to zero when 
Title: Economic sanctions
Content:  The United States embargo against Cuba began on March 14, 1958, during the overthrow of dictator Fulgencio Batista by Fidel Castro during the Cuban Revolution. At first, the embargo applied only to arms sales, however it later expanded to include other imports, eventually extending to almost all trade on February 7, 1962. Referred to by Cuba as "el bloqueo" (the blockade), the U.S. embargo on Cuba remains one of the longest-standing embargoes in modern history. Few of the United States' allies embraced the embargo, and many have argued it has been ineffective in changing Cuban government behavior. While taking some steps to allow limited economic exchanges with Cuba, American President Barack Obama nevertheless reaffirmed the policy in 2011, stating that without the granting of improved human rights and freedoms by Cuba's current government, the embargo remains "in the national interest of the United States".

In 1989, with the collapse of the Soviet bloc, Cuba witnessed its most devastating economic crises. Cuba's GDP plummeted 34% and trade between the nations apart from the Council of Mutual Economic Assistance (CMEA) declined by 56%. Between 1989 and 1992, the termination of traditional trade partnerships with the Soviet bloc caused the total value of Cuba's exports to fall by 61% and imports to drop by approximately 72%. This period is known as the Special Period. Supporters of the embargo and many international economists

Also in February 1962, the U.S. pressured members of the Organization of American States to expel Cuba, attempting to isolate it. In response to the Bay of Pigs, Cuba called for revolution in the Americas. These efforts ultimately failed, most notably Che Guevara in Bolivia, where he was isolated, captured, and executed. When the U.S. discovered that the Soviet Union had placed missiles in Cuba in 1962, the U.S. reacted swiftly in a showdown now called the Cuban Missile Crisis, which ended with an agreement between the U.S.

Fidel Castro's government seized private land, nationalized hundreds of private companies—including several local subsidiaries of U.S. corporations—and taxed American products so heavily that U.S. exports were cut half in just two years. The Eisenhower Administration then imposed trade restrictions on everything except food and medical supplies. As a result, Cuba turned to the Soviet Union for trade instead. The US responded by cutting all diplomatic ties to Cuba, and have had a rocky relationship ever since. In April 1961, a CIA-trained force of Cuban exiles and dissidents launched the unsuccessful Bay of Pigs Invasion against Cuba,

The ensuing years were marked by economic difficulty in Cuba, a time known as the Special Period. U.S. law allowed private humanitarian aid to Cuba for part of this time. However, the long-standing U.S. embargo was reinforced in October 1992 by the Cuban Democracy Act (the "Torricelli Law") and in 1996 by the Cuban Liberty and Democracy Solidarity Act (known as the Helms-Burton Act). The 1992 act prohibited foreign-based subsidiaries of U.S. companies from trading with Cuba, travel to

On 13 October 1960, the U.S. government then prohibited the majority of exports to Cuba – the exceptions being medicines and certain foodstuffs – marking the start of an economic embargo. In retaliation, the Cuban National Institute for Agrarian Reform took control of 383 private-run businesses on 14 October, and on 25 October a further 166 U.S. companies operating in Cuba had their premises seized and nationalized, including Coca-Cola and Sears Roebuck. On 16 December, the U.S. ended its import quota of Cuban sugar. The U.S. government was becoming increasingly critical of Castro's revolutionary government.
