Cuba
The Castro government gradually expropriated all foreign-owned private companies after the Cuban Revolution of 1959. Most of these companies were owned by U.S. corporations and individuals. Bonds at 4.5% interest over twenty years were offered to U.S. companies, but the offer was rejected by U.S. ambassador Philip Bonsal, who requested the compensation up front.[4] Only a minor amount, $1.3 million, was paid to U.S. interests before deteriorating relations ended all cooperation between the two governments.[4] The United States established a registry of claims against the Cuban government, ultimately developing files on 5,911 specific companies. The Cuban government has refused to discuss the effective and adequate compensation of U.S. claims. The United States government continues to insist on compensation for U.S. companies. In 1966-68, the Castro government nationalized all remaining privately owned business entities in Cuba, down to the level of street vendors.
