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.

Fidel Castro, after his first contacts with Brazilian President João Goulart’s special envoy Albino Silva, accepted well the Brazilian thesis which contains following: Denuclearization of the whole of Latin America and the embargo on atomic weapons delivery; Inspection by UN; Cuba would commit neither to export revolution nor to carry out any subversive activities; Cuba would be given guarantees for keeping its sovereignty and independence. The USA will accept the plan after negotiations. Russians “couldn’t think of anything better.”

Vidakovic has a conversation with Mikoyan on the USSR's guarantees to the independence of Cuba and the negotiations talks.

A telegram from the Yugoslav Embassy in Rio de Janeiro to the Yugoslav Foreign Ministry discussing the Cuban Missile Crisis and U.S.-USSR-Cuban relations. It says, the "American arguments in favor of the military blockade of Cuba are: firstly, they have solid proof that Cuba will get atomic weapons; secondly, Kennedy must take more severe measures because of the internal pressure, that’s why his option is blockade, although he is trying to transfer this issue to the UNO [United Nations Organization] in order to alleviate the pressure on himself; thirdly, transferring Cuba’s issue to the UNO he is creating a precedent against unilateral USSR actions in Berlin."
