The memorandum includes topics discussed between CPCz Secretary Vladimír Koucký and Cuban government official Carlos Rafael Rodríguez. Rodríguez lists points of misunderstanding between Cuba and other socialist countries. Discussion topics include Chinese publications in Cuba, Cuba's unique approach to socialist revolution, the proposed nuclear-free zone in Latin America, and building socialism under various conditions (e.g. Islam's role in Algeria), among others. Rodríguez encourages more communication among socialist nations to prevent misunderstanding.

In a report on the Cuban Communist Party, Bulgarian Embassy counselor S. Cohen discusses strengths and concerns with the Cuban goverment. The Cuban revolutionary movement debunked the theory of geographically determined fatalism, but also displays a strong dependence on the Latin American liberation movement (e.g. Jose Mari, Simon Bolivar) for inspiration instead of socialist principles. Cohen reports negative developments including the Cuban government’s growing ambition to rule the Third World revolutionary movement and strong belief in the Cuban armed struggle as a template for all national liberation movements. The Cuban delegation strongly endorsed armed struggle as the only means of socialist advancement at the Tricontinental Conference recently held in Havana. Bulgaria must remain close with the Cuban government to help it develop economically and mature politically.

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 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.
