Nikita Khrushchev and Jawaharlal Nehru discuss global disarmament, the Soviet Union's resumption of nuclear weapons testing, and the ongoing tensions surrounding Berlin. Khrushchev defends Soviet nuclear tests as a necessary response to perceived Western threats and the failure of disarmament talks, asserting that such actions are essential to safeguard the USSR and the socialist bloc. He reassures Nehru that access to West Berlin will remain unobstructed after the signing of a peace treaty with East Germany, though the legal basis would shift from occupation rights to agreements with the GDR. Both leaders emphasize their shared commitment to disarmament, but Nehru voices concerns that continued nuclear testing may derail global peace efforts and delay meaningful progress toward disarmament.

Gromyko informs Liu Xiao of the Soviet position and strategy in its negotiations with the United States and the United Kingdom for halting nuclear tests.

H.M.S. Reid sends instructions to the UK Embassy in Pretoria in preparation for a meeting with South African Secretary for Foreign Affairs Brand Fourie. Reid informs them that the Prime Minister wishes to send his concerns about the possibility of South Africa exploding a nuclear device.

Nye stated that at present the United States preferred to "concentrate on pressing South Africa to adhere to the NPT rather than continuing to enquire about the nature of the Kalahari facility." The State Department assessment was that while South Africa was capable of building a bomb at short notice, they did not actually plan to test one at this time.

Memorandum on UK position at Lagos Conference on Apartheid about Soviet allegations of South African nuclear weapons development.

J.S. Wall of the UK Foreign and Commonweath Office reports on a conversation with David Aaron of the US National Security Council on concerns about South Africa's possible nuclear testing facility in the Kalahari desert.

UN Representative Milko Tarabanov reported to the Bulgarian Communist Party Politburo recent developments of the Conference of the Eighteen-Nation Committee on Disarmament. The report summarizes the conference's work from November 1962-December 1962, the period following the Cuban Missile Crisis. Tarabanov reports that Western powers put forward two draft agreements calling for the cessation of nuclear tests in the atmosphere, under water and in outer space, and underground--the proposals were debated during the 17th United Nations session.

The Cubam Missile Crisis occurred during the conference's session. Main issues discussed after Cuban Missile Crisis included: suspension of nuclear tests, Soviet Foreign Minister Andrei Gromyko's proposal at the 17th session of the UN, ways to measure nuclear weapons testing, and military alliances (NATO).

Tarabanov also addresses the inter workings of conference members--Western, socialist, and neutral--including disagreements among Western powers. In summary Tarabanov adds that the prospect for cessation of nuclear tests is poor, but notes that the US may consider closing military bases, though not under pressure of the Soviet Union or neutral countries.

Having successfully executed a nuclear test explosion, Zhou Enlai describes the Chinese government’s motivation for pursuing atomic weapons capabilities. Zhou argues that the Three-Nation Treaty (Limited Test Ban Treaty) is insufficient, that the United States remains committed to nuclear proliferation despite the agreement, and that China seeks to end the monopoly that other nuclear powers have thus far exploited. Zhou also calls for the organization of a global, truly equal summit at which to discuss the issue of nuclear weapons testing and proliferation.

The Soviet Central Committee informs their Chinese counterparts that, in light of the arms reduction talks taking place in Geneva, Soviet nuclear assistance must cease. The Chinese had requested a sample atomic bomb and technical data, but the Soviet feared that doing so would imperil the efforts of the socialist countries in Geneva.

Khrushchev writes to Zhou outlining the Soviet Union's argument for the need to halt the testing of atomic weapons, and urges the Chinese to support and agree to the ban.
