PCB Politburo member Jorge Kolle Cueto asks on 7 March 1967 to inform the Czechoslovak Communist Party, "on behalf of the CC of the Bolivian CP," regarding "the situation in Bolivia… and his recent meeting with Fidel Castro." After four pages of discussion regarding the depressing internal political situation under 1964 coup leader, General René Barrientos, Kolle announced that "the party must necessarily prepare for the possibility of armed struggle in order to participate in the attempt to overthrow the current regime together with other leftist forces."

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.

The cable reveals serious misgivings by the Cubans with regard to Soviet handling of the crisis. Roy Inchaustegui was criticized by Castro for discussing the question of document authenticity about the missile bases instead of discussing Cuba's right to defense at the UN Security Council. Pavlicek reports the Council asked on Czechoslovakia's stance towards Castro's 5 Points. While responding with support, he still asked for an official viewpoint from the Czechoslovak government in Prague.

Calderio's visit to Prague in the aftermath of the Cuban Missile Crisis served to solidify the ties between Cuba and Czechoslovakia, relations that would persist until the end of the Cold War. Among the activities of Calderio's visit included attendance of 12th Party Congress of the Czechoslovak Communist Party, meeting with Cuban ambassadors to China, Czechoslovakia and Hungary, and a promise to attend the meeting of the Bulgarian Communist Party.

Fidel Castro's speech is the centerpiece of this cable from Pavlicek. Castro's rhetoric touched on the unity of the Cuban people, and their refusal to an "undignified agreement." Pavlicek predicts his speech will foster a great response both internally and externally. Castro also acknowledged the help provided by the Soviet Union and the anti-Soviet campaign mounted by counterrevolutionaries. Pavlicek's only complaint was a lack of emphasis on the "critical role" the Soviet Union has played in the negotiations to resolve the crisis. However, the reaction to Fidel's speech is one of calming the situation and a clear orientation for the Cubans.

Pavlicek's primary focus in this cable is the effect of the crisis on the national media. The Cuban media is stressing Castro's 5 Points, and some journalists are hesitant to report anything else. There is a slight thread of anticommunism and anti-Soviet sentiment breeding among the media, but these feelings are not widespread, according to Pavlicek. The press is holding off on coverage of all other events such as the Sino-Indian border conflict and Chinese support for Castro's 5 points until after his speech.
