This document dated November 29, 1981 is the final version of a letter from Enrico Berlinguer to Hu Yaobang, President of the Chinese Communist Party, in which he invites his Chinese counterpart to contribute to finding a solution to the situation that has developed in Central and Latin America, especially with regard to US interference in these countries.

The memorandum includes topics discussed between CPCz Secretary Vladimír Koucký and Cuban government official Carlos Rafael Rodríguez. Rodríguez lists points of misunderstanding between Cuba and other socialist countries. Discussion topics include Chinese publications in Cuba, Cuba's unique approach to socialist revolution, the proposed nuclear-free zone in Latin America, and building socialism under various conditions (e.g. Islam's role in Algeria), among others. Rodríguez encourages more communication among socialist nations to prevent misunderstanding.

Zhivkov lays out his perspective on the place of Bulgaria within the Communist Camp. He also talks about the Balkans and the rift between Bulgaria and Romania. Both leaders discuss the Chinese accusations of Soviet Revisionism. Raul Castro talks about the strength of the communist movements in Latin America and the prospects for successful social revolutions in Venezuela, Chile, Costa Rica, Uruguay, and Brazil.
