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.

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

The Czech Ministry of Foreign Affairs condemns Chinese authorities responsible for threats to the Czech Embassy in Peking, including the forceful holding of the ambassador of the CSSR and other officials and the tearing of the flag.

This transcript shows the Czech party elites choosing against violent repression of the mass protests in Wenceslas Square. More clearly than in almost any other Party document, the reasons for nonviolence are spelled out: such a solution would only temporarily "return calm," it would radicalize the youth, "the international support of the socialist countries can no longer be counted on," and "the capitalist states" might react with a "political and economic boycott."

This report includes information on economic cooperation projects between Czechoslovakia and China and on the political situation in both countries. While the Czechoslovak side focuses on the democratization of the country, China points to its consolidated Socialist system. Also attached are records of conversations between Jaromír Johanes, Li Peng, and Jiang Zemin.
