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.

In a secret supplement to information from the VIII Congress of the People's Socialist Party, Bulgarian delegates Abramov and Tellalov summarize answers that Blas Roca, the Cuban delegation head, provided the congress. Roca claimed that socialism is the end goal of the revolution, but it is not publicly discussed. He explained the Communist party's involvement in the revolution and July 26th Movement. Abramov and Tellalov also describe the reestablishment of relations and disagreements between Cuba and Yugoslavia, including discussions about weapons. Fidel Castro met with socialist country representatives and described Cuba's plans to nationalize enterprises, particularly American. During the congress Castro described the evolution of the July 26th Movement and the consolidation of Communism in Cuba. Abramov and Tellalov endorse Castro's leadership and review the Cuban military's strengths and weaknesses. There is a brief mention Sino-Soviet relations.

Boissevain reports on Fidel Castro. During a banquet held by the Egyptian ambassador, Castro speaks to Swiss Ambassador Masset of a decision to nationalize the former building of the U.S. embassy, currently in use by the Swiss embassy acting as U.S. representatives. Castro is noted as having "the air of one who is boasting to a trusted friend about how he has crossed an opponent." Boissevain thinks it best to keep on Castro's good side and requests an illustrated work of the Netherlands to be sent as a gesture of goodwill.

Dutch Foreign Minister Joseph Luns responds to Boissevain's two cables regarding Castro's proposal for an agreement with the United States. Luns is wary of Castro's request to use the Boissevain as the mediator, and urges caution and reserve. He asks Boissevain to keep him updated of any future developments, should Castro make a future proposal.

Boissevain writes in continuation of the previous cable regarding Castro's desire for a mediator in an agreement with the United States. The Swiss or Czech ambassadors are offered as alternatives by Boissevain. Castro also notes that the Cuban debt to the Soviet Union is far to large, although he still wishes to continue revolution, creating this impasse between Cuba and the United States.

Boissevain writes of a conversation Fidel Castro had with his wife, namely about how some ideals cannot translate into reality. Castro is interested in pursuing an agreement of some kind with the United States, and seeks to use Boissevain as the middle man. Boissevain is hesitant about any kind of deal with Castro, and asks for instructions on how to proceed.

The meeting of the Council of Ministers at The Hague revolved around the ongoing naval blockade of Cuba by the United States. The Dutch Assistant Secretary of State related that while the Americans are remaining firm on the Cuban situation, his visit to President Kennedy revealed he was very tense and was looking for a solution. The Foreign Ministry has yet to give an definitive stance on Cuba, but the primary concern for the Dutch Government was freedom of the sea and free flow of trade. The Minister of Justice concludes that while the government has no power to stop ships from going to Cuba, it does have the power to bar arms shipments.

A letter from Gideon Boissevain, the Dutch Ambassador to Cuba reporting to Amsterdam. The letter primarily concerns the press coverage in Cuba of the rising crisis. Particular attention is paid to the Soviet guarantees of Cuban security and the American responses to the discovered missiles. In Cuba there is fear of an invasion by the United States making use of foreign legionnaires, despite Kennedy's claims there is no plan for an attack on Cuba.
