János Kádár presents on his diplomatic trip to Moscow to the Hungarian Central Committee. Kádár first places the Cuban Missile Crisis in context. This includes describing the success of the Cuban revolution, US aggression towards Cuba, and the Cuban-Soviet military and defense agreement, which ultimately spawned the US’s unilateral military mobilization. Kádár then describes the Soviet Union’s strategy to achieve two goals: protect the Cuban revolution and preserve peace. He notes that Cuba and the Soviet Union disagree about how the crisis was resolved, but asks the congress of workers to show complete support of Soviet actions and successes.

The Bulgarian Embassy in Havana reports to the Central Committee of the Bulgarian Communist Party and the Bulgarian Ministry of Foreign Affairs on political, economic, and cultural developments in Cuba circa 1963. Cuba is politically united, but is experiencing economic hardship after the “Caribbean Crisis” primarily because of the US embargo. In the report, embassy staff reviews developments between socialist countries and Cuba throughout 1963. Some examples include communist aid to Cuba after Hurricane Flora and Cuba’s stance on Sino-Soviet relations. Bulgaria’s show of solidarity resulted in concrete political, economic, and cultural cooperation. Embassy staff notes the drawbacks and benefits of Bulgaria’s relationship with Cuba.
