Bulgarian Ambassador to Cuba Stefan Petrov analyzes Cuba’s domestic and foreign policies in an informational report to Bulgarian leader Todor Zhivkov. Petrov criticizes Cuban Communist Party policies and claims they are incompatible with Marxism-Leninism (e.g. Cuba’s focus on conflict between imperialism and national liberation rather than socialism and capitalism). Cuba has adopted an anti-Soviet attitude and believes Cuban leadership is the vanguard of communism. Petrov reviews Cuba’s conflicting relations with Latin American communist parties and Cuba's support to guerilla movements in the region. Petrov notes that Bulgarian-Cuban relations remain positive.

First Secretary of the Bulgarian Embassy to Cuba A. Hubenov describes a Latin American communist party conference held in Havana, November 1964. The parties secretly discussed their struggle against imperialism and the expansion of communist revolutions in Latin America and Cuba's assistance to that struggle. Conference deliberations included a discussion of the Sino-Soviet split and the fear of factions within the communist movement.

The Bulgarian Embassy in Havana reports to the Central Committee of the Bulgarian Communist Party and the Bulgarian Ministry of Foreign Affairs on political, economic, and cultural developments in Cuba circa 1963. Cuba is politically united, but is experiencing economic hardship after the “Caribbean Crisis” primarily because of the US embargo. In the report, embassy staff reviews developments between socialist countries and Cuba throughout 1963. Some examples include communist aid to Cuba after Hurricane Flora and Cuba’s stance on Sino-Soviet relations. Bulgaria’s show of solidarity resulted in concrete political, economic, and cultural cooperation. Embassy staff notes the drawbacks and benefits of Bulgaria’s relationship with Cuba.

In a report to First Secretary of the Central Committee of the Bulgarian Communist Party, Todor Zhivkov, the Minister of Foreign Trade, Georgi Kumbiliev, reviews Cuba’s need for weapons and credit. Kumbiliev relays a weapons request for Latin American revolutionary movements and an extension of financial assistance to Cuba. Kumbiliev advises Zhivkov to respond to the Cuban government’s requests and consider providing surplus Bulgarian weapons free of charge and extending a 5-year-term loan to Cuba starting 1 Jan 1963.

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.

The ambassador gives an assessment of the Cuban domestic and foreign policy. He characterizes Fidel Castro as an adventurer and points to certain communist party decisions that are incompatible with the Marxist-Leninist doctrine.

Head of the 1st Administration of the Ministry of the Interior Josef Houska reports a complaint by the Brazilian government regarding to Czechoslovak assistance of transporting guerrilla fighters from Cuba to Latin America. Brazilian government issued an official warning that relations between Brazil and Czechoslovak could be deteriorated in connection with the support for Cuba. Houska says Brazilian officials' argument could be proof that Czechoslovak specially selected officials making technical arrangement for the transits belong to some section of the Czechoslovak civil service. However, the Czechoslovak authorities cannot be blamed that they go along with the activities of the Cuban Embassy in Prague, which controls the transport of the guerrillas since an embassy is entitled to engage in full diplomatic activities in a friendly country. Houska argues that the Brazilian government does not have conceret evidence for the direct accusation of Czechoslovakia. The position of the Brazilian Ministry of Foreign Affairs could have been the result of pressure by ultra-reactionary forces in domestic policy which are concerned by the opposition activities in Brazil and abroad.
