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.

Rodriguez met with Koucky to clarify misunderstandings which could possibly arise because the reasons were not explained for Cuba’s positions on issues of the international communist movement, and for speeches and statements of some leading Cuban comrade.

Meeting between Raul Castro, Bohumir, Lomsky, and Langer. Castro informed Lomsky that internal danger has been eliminated, and contra-revolutionary and anti-government groups operating directly in Cuba have been broken up and practically destroyed. They evaluated the strategy of the cuba's defense, revised operational plans, and carried out number of changes. They originally approached the CSSR with a plea for a shipment of 200 pieces of 30 mm double cannons. The current situation, however (especially the situation in the DRV), is forcing them to ask for 30 mm cannons again.

Report on visit of Cuban Delegation in Czechoslovakia and conversation on 16 April 1965. This document contains information about visit of the Czechoslovak military delegation in Cuba on 30 March - 9 April 1965. There are attachments to the document: draft of the resolution, the report, report on important conversations in connection with the visit. The visit occurred at the time of heightened acts of aggression of the USA against the Democratic Republic of Vietnam, and thus it was regarded as highly important in Cuba. It contributed to strengthening of Cs. Cuban friendship and to strengthening of the friendship in arms of our armies.

Memorandum of Conversation between Czechoslovak Communist Party official Vladimir Koucky and Cuban Communist Party official Carlos Rafael Rodriguez that took place in Prague.

Czechoslovak Intelligence reports on a possible assassination plot against Castro and a possible coup against the Revolutionary Government in Havana. The document details the plot being planned by individuals in Havana including smuggling explosives into a public celebration for 1 May. Microfilms containing information on the plot including the organizers and place of action. It is obvious from this correspondence that the planned assassination and coup against Castro are part of the Bay of Pigs Invasion.

The record and attached resolution concerns the final decision by the Politburo of the Czechoslovak Communist Party to send arms and "special technology" to Cuba. Among the arms shipped are 2 mobile artillery batteries, 50 million 7.92 mm bullets, and military specialists to aid the Cuban military in the construction of anti-aircraft defenses on Cuban territory. This would prove to be fruitful for the Cubans in the coming Bay of Pigs Invasion.

The report concerns requests from Cuba for shipment of arms from Czechoslovakia, along with providing advisors to the Cuban military. Among the arms being transferred are Czechoslovak fighter planes, automatic rifles and ammunition, mobile artillery, and anti-aircraft guns. Clearly the Cuban desires for arms were fueled by fears of American attack, which would come to fruition in the 1961 Bay of Pigs Invasion.

These concern preparations by the Czechoslovak government for the visit of Ernesto "Che" Guevara on 23 October 1960. The primary topics of discussion are economic assistance to Cuba and advice on raw material production, as Cuba was in the process of nationalizing its economy.

This includes further orders of weapons shipment to the Cuban revolutionary government under the guise of "special materials." Also included is a short profile on Raul Castro, member of the Cuban delegation, as well as the details of his stay in Czechoslovakia.
