Prague dispatched delegates to the Eighth Congress of the PSP in August 1960. Speaking at the gathering, the Cuban communist leader, Blas Roca Calderio, effectively offered his stamp of approval to Castro before the Czechoslovakian guests, recognizing him as a “new phenomenon in Latin America’s history.” In their comments, the Czechoslovaks demonstrated their satisfaction with the deepening influence of the Cuban communists within the country’s socio-political transformations, which held the serious potential to increase the significance of the Cuban revolution in the eyes of the Soviet Union and the other Socialist states.

After talking with the member of the PSP's Central Committee, Severo Aguirre, Prague’s Communist Party leaders saw a glimmer of hope for the further radicalization of the revolution:  the fact that the “bourgeois” leaders of the revolutionary army, the Castro brothers, and Ernesto “Che” Guevara, relied on the people’s army, on which the communists had significant influence.

The Cuban communists asked the Soviets for help exposing the government's “terror” and the interference of “American imperialism” in Cuba’s affairs. The CPSU’s Central Committee agreed to support the fight of the Cuban people in the press, radio, and public organizations in the closing months of 1958.

Castro and Husák discuss recent developments in Cuba and Czechoslovakia. Castro recounts the history of the Cuban revolution, while Husák explains the crisis of 1968-1969 in Czechoslovakia.
