Treaty establishing the Warsaw Pact in response to the integration of West Germany into NATO.

The Polish Embassy in Romania reports on trends in Romanian foreign relations. There are signs of rapprochement with the other socialist countries in the Warsaw Pact after Romania reversed course to join Comecon. Yet Ceaușescu continued to court China and the United States as well.

Hungarian Ambassador to Bulgaria Karoly Prath summarizes developments on Bulgarian-Cuban relations gathered from Hungarian-Bulgarian diplomatic contacts. Bulgarian-Cuban relations were not adversely effected by the Cuban Missile Crisis. The relationship is dominated by economic development (e.g. the expansion of trade, specialist exchanges, Bulgarian loans to Cuba, the root causes of Cuba's economic difficulties). Prath also discusses Bulgarian concerns over the influence of China on Cuba.

Todor Zhivkov reports his impressions of his recent visit to Cuba. The report is a rough outline of topics ranging from advancements in the Cuban revolution since 1959 to prospective ways to improve Bulgarian-Cuban relations. In the report Zhivkov presents his assessment of the Cuban Communist Party congress. Party documents show a maturing understanding of Marxism-Leninism and a new clarity in the Cuban Communist Party as a whole. Zhivkov’s report includes examples of Cuba’s self-criticism and Zhivkov’s own criticism of Cuba’s leadership. Some topics of discussion include: cultural and economic specialist exchanges, the price of sugar, Cuba’s increased collaboration with Soviet Union and other socialist nations, and economic subsidies and aid.

The report details Bulgaria’s preparations for a Cuban delegation and the visit itself. The author offers both praise and criticism of Cuban leadership. There has been positive progress in Cuba in recent years, yet underlying problems remain (e.g. the economy lacks planning). The Bulgarian government devised the visit as an opportunity to teach the Cuban delegation about building state socialism. The report includes an overview of the Cuban delegations visit. Discussions during the visit involved Cuban economic growth and barriers, China, Romania’s non-interventionist policies, Nixon’s 1972 visit to Moscow, and economic and scientific cooperation (particularly between Bulgaria and Cuba).

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. Tellalov and Bashev contextualize Cuba's development both nationally and internationally. Cuba's primary concerns are related to its economy (re: housing, rationing, embargo). 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.

The Bulgarian Communist Party Politburo report includes three main documents: a protocol and resolution with notes, a top secret information note, and a top secret protocol from 30 July 1970. The first section includes the Politburo's approval of the delegation's negotiations with Cuba, proposals to restructure economic partnership, and the Bulgarian delegation's statements on miscommunication between Cuba and Bulgaria. The second section, top secret information note, summarizes important exchanges during the Bulgarian visit to Cuba (e.g. Zhivkov's discussion on the importance of economic cooperation (COMECON) to the development of socialism). The third section, the top secret protocol, includes portions of a conversation between Bulgarian delegation and Cuban Politburo members. Castro summarizes ideas exchanged during the state visit.

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.
