In a conversation between Kliszko and Raul Castro, a referral was made to the position assumed by the Minister of Industry in Cuba, Ernesto Guevara, at the economic seminar of Afro-Asian countries in Algeria in February 1965. Castro stated that he was not prepared to discuss the essence of the issue, e.g. the extent of aid from socialist countries to developing countries, but he felt Guevara's comments were extreme and out-of-place at the seminar.

Zhivkov lays out his perspective on the place of Bulgaria within the Communist Camp. He also talks about the Balkans and the rift between Bulgaria and Romania. Both leaders discuss the Chinese accusations of Soviet Revisionism. Raul Castro talks about the strength of the communist movements in Latin America and the prospects for successful social revolutions in Venezuela, Chile, Costa Rica, Uruguay, and Brazil.

Conversation for the record between Zhivkov and Castro during a four-day-long state visit of the Cuban leader to Bulgaria. Among the main issues discussed was the state of economic development in both countries, their relations with Albania, China, Romania and Yugoslavia; the Cuban foreign policy in Africa and the Caribbean; the civil war in Angola; the battle for the Third World.
