Hungarian ambassador to Czechoslovakia Lajos Cséby summarizes Deputy Head of the Sixth Main Department [of the Czechoslovak Ministry of Foreign Affairs] Stross’s report on relations between Cuba and Czechoslovakia. Stross reports friendly relations between the two countries, which did not experience difficulties during the Cuban Missile Crisis. Stross outlines Cuba’s problems, economically and politically, and believes that Cuba’s revolutionary success depends on its economic growth. Cuba misunderstood the Soviet Union’s approach to the Cuban Missile Crisis. This led to signs of Chinese influence on Cuban politics, which Stross believes are reversing since Castro’s [1963] visit to the Soviet Union.

In a memorandum, Konstantin Tellalov, Head of the Foreign Policy and International Relations Department of the Central Committee of BCP, and Foreign Minister Ivan Bashev evaluate Cuban-Bulgarian relations.

Cuba's leadership continues to display a limited understanding of Marxism-Leninism, scientific planning (central planning), and the importance of COMECON. Taking into consideration the Bulgarian delegation’s recent visit to Cuba, they stress the importance of Cuba's success and the need for a radical, all-embracing commitment to relations.
