Bulgarian Ambassador to Cuba Stefan Petrov analyzes Cuba’s domestic and foreign policies in an informational report to Bulgarian leader Todor Zhivkov. Petrov criticizes Cuban Communist Party policies and claims they are incompatible with Marxism-Leninism (e.g. Cuba’s focus on conflict between imperialism and national liberation rather than socialism and capitalism). Cuba has adopted an anti-Soviet attitude and believes Cuban leadership is the vanguard of communism. Petrov reviews Cuba’s conflicting relations with Latin American communist parties and Cuba's support to guerilla movements in the region. Petrov notes that Bulgarian-Cuban relations remain positive.

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.
