The final instructions for the Czechoslovak delegation en route to Geneva for the ENDC in November 1967.  The treaty was mostly finished by this time; only the final details remained. Denunciation of US foreign policy and prevention of West Germany’s nuclear weapon acquisition reappear in these instructions.

A report produced by the Czechoslovak foreign ministry in August 1963 recommending the ratification of Limited Test Ban Treaty (LTBT).  One of the key goals of early Czechoslovak engagement in the ENDC was to reject a nuclear test ban, based on their rejection of any verification measures. However, once the Soviets agreed to the LTBT with the US and the United Kingdom, the Czechoslovak foreign ministry praised the agreement and attacked those (such as China) who resisted the measure. One interesting aspect of the treaty was the proposed role of depositary powers. The document indicates that the Soviets were interested in being a depositary power to the LTBT in order to prevent ratification by governments not recognized by the USSR, most notably West Germany and the Republic of China. The issue of depositary powers reappeared later on, in the NPT as well.

An undated memorandum, produced most likely in the late spring of 1963 (most likely in May) that outlines Soviet thinking on the most recent discussions with US representatives on the nuclear nonproliferation treaty. The memorandum is crystal clear that the key goal for Soviet negotiators was to avoid West German control over nuclear weapons. This is why Moscow opposed the idea of a Multilateral Nuclear Force. However, Soviet officials also admitted that it was better to agree to a treaty that did not explicitly prohibit a multilateral nuclear force as long as their US counterparts committed not to let West German authorities have an authoritative role in authorizing nuclear-weapon use

Czechoslovakia participated in the Ten Nation Committee on Disarmament, a short-lived outfit which was mired in superpower infighting and consequently made no substantive progress. This letter, written from Czechoslovakia’s Foreign Minister Václav David to Prime Minister Viliam Široký, is nonetheless informative, as its attachment contains a memorandum outlining Soviet proposals for general and complete disarmament in three phases. 

Khrushchev and Ambassador Yamada discuss US nuclear testing, prospects for disarmament, and the challenges facing the Eighteen-Nation Disarmament Committee. They also review Soviet-Japanese political and trade relations, with Khrushchev expressing interest in expanding economic ties while criticizing US influence over Japan’s trade decisions.

Brezhnev discusses negotiations with the United States over the Non-Proliferation Treaty.

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.
