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.

Deputy Forieng Minister Lubomir Angelov transmits to Bulgaria's embassy in Turkey information from Bulgarian Ambassador to Great Britain Radenko Grigorov. Angelov's message is handwritten and reports news about Soviet and US submarine presence in the Mediterranean, which initially Grigorov acquired from Turkey's ambassador to Great Britain.

Bulgarian Embassy in Athens staff member Atanasov reports on Greek media accounts of military preparations to the Bulgarian Ministry of Foreign Affairs. According to Atanasov, Greek newspapers report preparations include Soviet movements in the Mediterranean in response to US submarines carrying Polaris missiles, Bulgarian maneuvers near the Greek and Turkish borders, and an anticipated NATO forward strategy in Greece. Atanasov adds that NATO is preparing the defense of possible attacks on Greece.

UN Representative Milko Tarabanov reported to the Bulgarian Communist Party Politburo recent developments of the Conference of the Eighteen-Nation Committee on Disarmament. The report summarizes the conference's work from November 1962-December 1962, the period following the Cuban Missile Crisis. Tarabanov reports that Western powers put forward two draft agreements calling for the cessation of nuclear tests in the atmosphere, under water and in outer space, and underground--the proposals were debated during the 17th United Nations session.

The Cubam Missile Crisis occurred during the conference's session. Main issues discussed after Cuban Missile Crisis included: suspension of nuclear tests, Soviet Foreign Minister Andrei Gromyko's proposal at the 17th session of the UN, ways to measure nuclear weapons testing, and military alliances (NATO).

Tarabanov also addresses the inter workings of conference members--Western, socialist, and neutral--including disagreements among Western powers. In summary Tarabanov adds that the prospect for cessation of nuclear tests is poor, but notes that the US may consider closing military bases, though not under pressure of the Soviet Union or neutral countries.
