The Yugoslav Foreign Ministry relays to its embassies a summary of the Brazilian proposal on the Cuban Missile Crisis which, they say, mainly includes: the denuclearization of Latin America with inspections, Cuba's commitment to not "export" revolutionary operations, and guarantees to Cuba for sovereignty and independence. Allegedly, Castro welcomed the idea of the above plan. Brazil thinks that the USA could accept it after negotiations.

Brazilian President João Goulart emphasizes that the possibility of an adequate solution (to the Cuban Missile Crisis) could be increased if there were measures to suspend the quarantine (blockade) immediately, followed by corresponding and effective stoppage of weapons shipment to Cuba as well as determining obligations to prevent the spreading of nuclear weapons and the installation of bases. In his opinion the danger of war could increase significantly and worries of Brazil would grow as far as its own security was concerned, if such bases were installed in Cuba or any other part of LA. He also brought to the attention the proposal of Brazil in the UN for the denuclearization of Latin America.

A telegram from the Yugoslav Embassy in Rio de Janeiro to the Yugoslav Foreign Ministry about a meeting with Brazilian President João Goulart. Barišić says Goulart considers that everything must be done to prevent the beginning of war, because war would bring unpredictable catastrophe and it would be hard to extinguish it if war operations start. Goulart also shares his opinion that negotiations are necessary, and that Cuba must be prevented from becoming an atomic base for it could be the constant cause of war dangers.
