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.

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

A record of the conclusions of the 186th meeting of the Political Bureau of the Central Committee of the Communist Party of Czechoslovakia, which met on March 6, 1962.  The attachment includes the initial instructions for the Czechoslovak delegations to the first meeting of ENDC. The document testifies to the strong preoccupation with West Germany’s re-armament, and the possibility of West Germany nuclear-weapon acquisition. Czechoslovakia travelled to Geneva with a goal of avoiding this outcome at any cost. Although the document offers a broad overview of the “lay of the land” ahead of the first meeting of ENDC, it is the focus on West Germany that is the most obvious here

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. 

This memo to Vasily Kuznetsov, First Deputy Foreign Minister of the USSR, includes proposed amendments and clarifications to various articles and sections of the NPT. Topics of the proposed amendments include an emphasis on the continued importance of sovereignty and territorial integrity and the exchange of research and technology on peaceful uses of nuclear technology. The document also describes how to proceed in negotiations with the American side, as well as with several Warsaw Pact countries, and to telegraph once the requests in the memo have been delivered.

This decree tasks the Soviet MFA with obtaining an agreement from fellow members of the Warsaw Pact on the USSR's suggested revisions to the NPT.

Andrei Gromyko describes the diplomatic measures he deems necessary to ensure the adherence of influential nations and countries in the Socialist sphere to the NPT.
