Documents related to East Germany's protest against the intended establishment of a Chinese trade representation in West Berlin. The East German Ministry of Foreign Affairs stresses that West Berlin cannot be regarded as part of West Germany. Therefore, by initiating diplomatic relations with West Berlin without considering the existence of the internationally acknowledged Four Power Agreement on Berlin between the US, Britain, France, and the Soviet Union, China is deliberately acting against the interests of East Germany.

Comrade Schneidewind and Ambassador Peng Guangwei discuss reports that China may be establishing diplomatic relations with West Germany

In anticipation of a visit by Zhao Ziyang to East Germany, the Ambassador of the GDR in Beijing reports on China's economic reforms, the leadership within the Chinese Communist Party, and China's relations with the GDR, the Soviet Union, the United States, and Japan.

French diplomat in Beijing Etienne Manac’h writes that "China is very concerned by the trend towards détente emerging in East-West relations."

This document offers an East German assessment of Romania's attitude towards China. It emphasizes that the Romanian Communist Party approves of the Chinese Maoist line and agrees with Beijing's domestic and foreign policies. Romania's foreign policy is said to attribute the same importance to relations with China as to relations with the Soviet Union. It also notes that the Romanian government has given more publicity to the resumption of diplomatic relations between China and West Germany than it did to similar moves between East Germany and India. The authors identify an anti-Soviet bias in the Romanian position, which the authors believe undermines the unity of the Socialist countries.

This document is a demarche to be delivered to the Chinese ambassador in East Berlin on the occasion of China's establishment of diplomatic relations between West Germany and the People's Republic of China (PRC). The demarche says the West German government is pursuing a revisionist policy and does not accept the post-war separation of Germany. It assesses the role of Bonn in international relations as detrimental to the entire Socialist camp and regards the visit of West German Foreign Minister Walter Scheel to Beijing, as well as diplomatic relations between China and West Germany, as damaging the interests of East Germany. The author asks China to reconsider this policy, with reference to East Berlin's support for the PRC's territorial claims to Taiwan/Formosa.

According to a marginal note, the demarche was never delivered.
