The embargo against Cuba started in October 1960 after Cuba exercised its sovereign right to nationalize U.S. properties. The move came as a response to the Eisenhower administration's cancellation of the sugar quota, which stipulated the import of 700,000 tons of sugar to Cuba. The administration had also prohibited delivery of oil to the island, forcing Cuba to buy from the Soviet Union. On Washington's orders, multinational oil companies refused to refine the Soviet oil, leaving Cuba no choice but to nationalize the companies.
