The Soviet Union sent a delegation to the All-China Assembly of People's Representatives in Beijing. During this time, A.N. Kosygin and Mao Zedong discussed Vietnam including American military actions, Soviet assistance and support, and their socialist path. The conversation then moved towards a debate over spheres of military influence. The Soviets believed that they and the Chinese should unite to fight against American capitalism, but Mao stated that the Soviets should protect Europe and Chine should protect Asia. Other issues addressed included imperialism, Africa, the United Nations, foreign relations, and the concern over factions between communist states and internal factions within parties.

Drozniak forwards a report from US Assistant Secretary of State for Inter-American Affairs [Edwin M.] Martin. Martin says that the Americans are well-informed of the military situation in Cuba, that Cuba does not possess nuclear weapons (nor will they be likely to because the USSR did not give such weapons to China, so why would they give them to Cuba?), that the level of the Cuban economy is twenty-five percent lower than the period before Fidel Castro came to power and Cuba is much more economically dependent on the USSR, and finally that any military invasion or complete blockade of Cuba would be considered an act of war by the USSR.
