The Cuban gross domestic product declined at least 35% between 1989 and 1993 due to the loss of 80% of its trading partners and Soviet subsidies. This loss of subsidies coincided with a collapse in world sugar prices. Sugar had done well from 1985 to 1990, crashed precipitously in 1990 and 1991 and did not recover for five years. Cuba had been insulated from world sugar prices by Soviet price guarantees. However, the Cuban economy began to improve again following a rapid improvement in trade and diplomatic relations between Cuba and Venezuela following the election of Hugo Chávez in Venezuela in 1998, who became Cuba's most important trading partner and diplomatic ally.
