Zhou Enlai speaks with head of the Colombian House of Representatives delegation to China, José Ancizar Lopez, about an initiative to establish a nuclear weapons free zone in Latin America. Lopez agrees that nuclear weapons should not be used, but nuclear energy for medicine and other peaceful uses is good. Zhou calls on Latin America and Africa to take the initiative on preventing the use of nuclear weapons.

As a result of the commission, a draft treaty has been prepared for the creation of a Nuclear Weapon Free Zone. Brazil and Mexico have rival approaches to denuclearization.

The Chinese Ambassador to Vietnam reports that the United States is working through the United Nations to prevent Puerto Rico, Guantanamo, and its others holdings in Latin America from being included in any "Latin America Nuclear-Free Zone." The Ambassador suggests that this is an attempt to distract Latin American citizens from their campaign against American military bases in the region.

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.
