The conversation between Castro and Gomulka took place on the initiative of Castro. Parties discussed the following topics: (1) relations between the UPSR and the PUWP, (2) the issue of the legalization of the Cuban Revolution, (3) the Situation in Vietnam, (4) Cuba and the Current Situation in Latin America, (5) the position of the PUWP with regard to the conference of 81 parties, and (6) the attitude of the socialist camp towards Cuba.

During a trip from Orneta to Katowice, Raul Castro and Zenon Kliszko had conversation on the following topics: (1) assessment of the position of the Italian Communist Party, (2)assessment of the position of the Romanian Workers’ Party, (3) the UPSR and other Communist Parties in Asia, and (4) the Matter of a Former Member of the National Leadership UPSR – J. Ordoqui. For the Polish side, the program of the Italian Communist Party is not clear, particularly with regard to the question of establishing a uniform workers’ party.

During his visit in Poland, Castro relates Cuba's position on a conversation taken place in Moscow and why it may be of interest to the Cubans. Gomulka raises the issue of the missiles. In Gomulka's opinion two factors were decisive: contradictions which arose within the socialist camp and the policy which was conducted by Khrushchev. Gomulka is assured that US is capable of conducting a war with Cuba by way of conventional weapons, it does not have to use nuclear weapons. It is clear that the socialist camp and the USSR cannot defend Cuba in any other way but by using nuclear weapons. If a conflict is meant to be, then it will be a nuclear conflict, there is no other way. Gomulka further raises a question whether to go into a nuclear war or not. Castro disagrees with a manner nuclear weapons were withdrawn from Cuba by Soviets. Khruchshev explained that he did not have time. Per Gomulka, Khrushchev conducted a policy which was not thought-out and which was all-out. Gomulka further discusses his talks with Chinese and Vietnamese comrades re: nuclear weapons issue.

An excerpt on Cuba from Communist Party of the Soviet Union General Secretary Leonid I. Brezhnev's secret speech, “About Current Problems of the International Situation and the Struggle of the CPSU for the Cohesion of the World Communist Movement,” to the CPSU CC Plenum on 9 April 1968.

A visit of Soviet Premier Alexei Kosygin from 26-30 June 1967 prompts this report from the Mexican Embassy in Havanna to the Secretary of Foreign Relations in Mexico City. They discuss: the position assumed by the Cuban Government and Communist Party in relation to Latin America, the Middle East and Vietnam, the internal administration of Cuba and the political operation in Cuba.

Jelen discusses a conversation he had with [Foreign Minister Raúl] Roa [García] on 9 September. They discussed diplomatic visits, UN delegation sessions, and growing tensions in the 'Cuban situation' and possible US military action against Cuba.

There is an opinion among a small group of the heads of Latin American diplomatic posts that the US would push through the sanctions against Cuba, except for the military ones, as far as possible.

Boissevain writes of the continued presence of Russian military and economic advisors in Cuba, which are causes for concern. The ongoing question is for how long they will remain in Cuba and when do they leave. Boissevain says that last week approximately 1,000 advisors left the country, but with some note of resistance. However, the departure for them is a great relief for the average Cuban and Russian alike.

Van Roijen continues on the conversation he had with U.S. Secretary of State Dean Rusk from the last cable. Rusk believes Cuba may be aligning more with China and is factoring in Chinese interests in Cuba. However, Rusk also saw Chinese initiatives in North Korea and North Vietnam. The relationship with China is, in his words, "not a long-term worry like Moscow but a short-term worry."

The cable concerns a conversation between Dutch ambassador J. Herman van Roijen and U.S. Secretary of State Dean Rusk. Rusk said the Cuban issue still was a source of concern, with the upcoming anniversary of the Cuban Revolution, and was concerned about Havana in particular. Rusk conjectured that one of three things would happen: 1) Castro would announce joining the Non-Aligned Movement; 2) The extremists within the Communist Party would overthrow Castro; 3) A revolution against both Castro and the Russians would be mounted. The conversation concludes with Rusk complimenting President Kennedy for his aggressive yet prudent stance against the Soviets during the crisis.
