The cable relays an important development in regards to press coverage of the resolution of the Cuban Missile Crisis. There are strict controls and reviews to be placed on news from the Soviet Union, and there is to be no publications by Presna Latina about peaceful coexistence or solidarity with the Soviet Union, about export of arms, etc. until a resolution has been reached. Khrushchev's name is not to be mentioned anywhere. There are also strict limitations placed on foreign correspondents and journalists.

Mikoyan's talks with the Cubans appears to be stalling, according to Pavlicek. The Cuban delegation is adamant about Castro's 5 points, stubbornly refusing any inspection of the missile bases, especially by the UN. Pavlicek also reports on a reception held the previous day at the Soviet Embassy in Havana. It drew a large crowd, and was marked by "warm feelings and openness," but discussions of the Soviet Union's handling of the crisis remain in doubt.

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.

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 report details a meeting between Deputy Foreign Minister Hajek with Cuban Foreign Minister Raul Roa. After a dinner banquet which is attended by all members of the Cuban foreign ministry and the Czechoslovak embassy, Hajek and Roa pay a visit to Ernesto "Che" Guevara, Chairman of the Cuban National Bank. Conversations ranged from Cuba's international status to ways of thwarting American aggression. It is noted that Guevara was highly paranoid of an American attack on Cuba.
