François Duvalier
Cuba

After Fulgencio Batista (a friend of Duvalier) was overthrown in the Cuban Revolution, Duvalier worried that new Cuban leader Fidel Castro would provide a safe haven for Haitian dissidents.

Duvalier enraged Castro by voting against the country in an Organization of American States (OAS) meeting and subsequently at the United Nations, where a trade embargo was imposed on Cuba. Cuba answered by breaking off diplomatic relations and Duvalier subsequently instituted a campaign to rid Haiti of communists. This move severed Haitian relations with Cuba for 38 years until the two countries re-established relations in 1997.
