Vidaković tells the Yugoslav Foreign Ministry that Fidel Castro is very stubborn and that most of the negotiation talks that are taking place are just empty words.

Pinto analyzes Fidel Castro's decision to accept the “unilateral inspection,” when, beforehand, he always rejected inspection of this character.

Pinto meets with Anastas Mikoyan and Fidel Castro to discuss Brazilian-Soviet-Cuban relations.

Pinto believes that the immediate visit of the UN Secretary-General U Thant to Havana will be of major importance and, he is under the impression that the Cuban government is disposed to make important concessions in direct negotiations with him [U Thant].

Pinto tells the Foreign Ministry that he met with the Cuban Minister of External Relations, Raul Roa, but did not receive the Ministry's telegram message in time to ask Roa their question about the upcoming commission of the United Nations to Cuba and the Cuban government's affirmation that it would not accept any type of audit or inspection.
