Kudryavtsev and Fidel Castro discuss several points of business, including Kennedy and Krushchev's conversation at their Vienna meeting, the US invasion of Cuba, Yuri Gagarin's trip to Cuba, and the visit of two Cuban Majors to the Soviet Ministry of Defense.

Kudryavtsev delivers the text of Khrushchev's reply to Kennedy's April 18 message, and Dorticos and Fidel Castro praise the text of the message and Soviet support for Cuba. Kudryavstev infroms Castro of the granting of the Cuban governments request for various military equipment, including aircraft and specialists, from the Soviet Union.

At a screening of the film "Two Hours in the USSR," Kudryavtsev informs Fidel Castro that after analyzing the remnants of the US rockets handed over to the Soviets by the Cubans, Soviet scientists have determined that Soviet rocket technology is superior to that of the Us.

Kudryavtsev and Castro discuss diplomatic normalization between the USSR and Ecuador and a CPSU CC letter directed at restoring global unity of the Communist movement, and a report from Inchaustegui suggests renewed US attacks against Cuba.

Gromyko reported on his meeting with Kennedy. The Soviet representative argued that Cuba was never a threat to the US and Washington should end its hostile activities against Havana. He also warned Kennedy of the possibility of nuclear war in the event of an invasion of Cuba. Gromyko reiterated the Moscow's intention of supporting Cuba only in economic and defensive issues. Kennedy, however, pointed out that it was difficult to explain the surge in Soviet military aid to Cuba. The US president reaffirmed that Washington did not have any plan to invade Cuba, at least after Bay of Pigs and Operation Mongoose. The US was only preventing actions that could have led to war. Gromyko reemphasized the peaceful rivalry of the two ideological systems and proposed a meeting between the two leaders.

Mikoyan reported his conversation with US Representative to the UN Stevenson. The issues discussed include: An American non-aggression commitment against Cuba, the removal of the "quarantine", the methods for control of dismantling and dispatching of missiles, the normalization of relations between the US and their Latin American allies with Cuba, the liquidation of the US base in Guantanamo, the US proposal to remove ground-air missiles from Cuba, and the preliminary agreement between the US and the USSR over the issues to be discussed by the Security Council.

Mikoyan discusses the results of a meeting with Stevenson. The two discussed the quarantine in Cuba, the dismantling of weapons, the possibility of the Soviets and Americans coming to agreements over the issues to be discussed by the UN Security Council and the possibility of normalization of relations with Cuba in the future.

The U.S. allows Soviet ships to arrive at Cuba for the hastening of the removal process.
