Khrushchev makes the opening statement to the secretaries of the CC's of Communist and Workers' Parties of Socialist Countries at a conference in Moscow. The purpose of the conference is to discuss the preparation and conclusion of a German peace treaty.

Representing the SED CC delegation, Ulbricht writes to Khrushchev requesting a meeting with the CPSU CC presidium, for which he outlines the topics necessary for discussion. Topics include the West Berlin question and the need for an agreement between Western powers and the USSR, and a treaty between the GDR and West Germany to establish territorial sovereignty.

Ulbricht writes to Khrushchev discussing a peace treaty with Western powers. He mentions that the Bonn government threatens to repeal its trade treaty with the GDR if the peace treaty is concluded with both German states, and the economic problem this would pose for the GDR.

Ulbricht writes to Khrushchev regarding proposals for a peace treaty/ non-aggression pact to resolve the West Berlin issue. He also discusses further plans for economic development in the GDR to "catch up" with West Germany.

The Ministry of Foreign Affairs of the GDR asks the PRC to comply with the status of West Berlin as part of the GDR.

In this extraordinary conversation, Solidarity’s leader fears the collapse of the Wall would distract West Germany’s attention - and money - to the GDR, at the time when Poland, the trail-blazer to the post-communist era in Eastern Europe, desperately needed both. "Events are moving too fast," Walesa said, and only hours later, the Wall fell, and Kohl had to cut his Poland visit short to scramble back to Berlin, thus proving Walesa’s fear correct.

Khrushchev response to Ulbricht's 15 September letter regarding the closing of the border between east and west Berlin. He notes that since the Western powers were tending toward negotiation rather than confrontation over the crisis, "such steps which could exacerbate the situation, especially in Berlin, should be avoided."

1973 agreement between the Stasi and the KGB outlining their cooperative efforts to fight "ideological subversion" and uncover "the hostile plans of the enemy." Both secret services would also exchange information gathered by their espionage activities and provide mutual support in infiltrating agents. Of particular mutual interest was espionage against the Federal Republic of Germany and West Berlin. To this end, the KGB was permitted to recruit East German citizens, and the MfS would secure their ongoing contacts.
