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 was beginning to appreciate the political impact of US aid programs under the Alliance for Progress. The 1962 Czechoslovak report goes on to explore the many conditions of US aid under Kennedy’s Alliance for Progress, which included "a complete break in commercial intercourse with Cuba and the commencement of a strong opposition strategy against the labor movement."

Rodriguez met with Koucky to clarify misunderstandings which could possibly arise because the reasons were not explained for Cuba’s positions on issues of the international communist movement, and for speeches and statements of some leading Cuban comrade.

Meeting between Raul Castro, Bohumir, Lomsky, and Langer. Castro informed Lomsky that internal danger has been eliminated, and contra-revolutionary and anti-government groups operating directly in Cuba have been broken up and practically destroyed. They evaluated the strategy of the cuba's defense, revised operational plans, and carried out number of changes. They originally approached the CSSR with a plea for a shipment of 200 pieces of 30 mm double cannons. The current situation, however (especially the situation in the DRV), is forcing them to ask for 30 mm cannons again.

The Czechoslovak Deputy of the Minister of Foreign Affairs outlines Soviet policy towards the USS Pueblo Incident.

The report details Mikoyan's talks with President John F. Kennedy in Washington D.C. Among the topics of discussion were questions of hemispheres of influence, whether the Soviet Union promoted a revolution against the USA in Cuba, and whether Castro was made an enemy of the USA or was one from the beginning. Conduct of both nations with regards to the Cuban question is discussed at length, ranging from whether U.S. was correct in acting against a perceived threat to security, the conduct of the Cuban people, the extent of Soviet involvement in Cuba, and what military hardware would be left in Cuba after the removal of the nuclear missile bases.

The report to Novotny details the happenings of the Cuban Missile Crisis at that time. Great Britain feels out of the loop and hurt by not being consulted by the United States before it took action, while Kennedy is not backing down on the blockade until the missiles are removed. According to the message, it is unclear whether there are nuclear missiles in Cuba at all; an American army colonel admits to the UN that no traces have been found, despite hundreds of photographs taken. In Czechoslovakia, the situation is unchanged; troops are still on alert and awaiting combat orders, with morale running high. There are even some volunteers willing to go to Cuba and aid their Latin comrades.

This record of a 1987 conversation between the general secretary of the Chinese Communist Party, Zhao Ziyang, and Czechoslovak President Gustav Husák includes information on the political and economic situation in Czechoslovakia and China. Zhao Zhang explains changes in the leadership of the Chinese Communist Party. They also discuss the foreign policies of their respective countries, including relations with Japan and the US. Attached is a Slovak summary of the meeting, including details on technological cooperation between Czechoslovakia and China.
