Trading limitations meant that Cuba could not buy goods that had more than 10 per cent of American material, origin or technology. The barrier on trade meant that Cuba could not trade its nickel, sugar or any other raw materials to any company which also had the American market as a target. No ship which docked at a Cuban port could dock an American port within six months. Cuba had no access to the international financial markets because by law they were barred from engaging with Cuba. Cuba was therefore the only developing country in the world which has no access to financial assistance for development. Cuba also did not have any access to American technology.
