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.

This memorandum of conversation between the Head of the Far East Department in the East German Foreign Ministry Liebermann and Chinese Ambassador Peng Guangwei refers to China's intention to establish diplomatic relations with West Berlin. The East German side stresses the fact that countries such as Hungary and Bulgaria also established diplomatic relations with West Berlin taking into considerations the conditions posed by the international law and that China should do the same.

This is a memorandum on a conversation reflecting the differences of opinion between the head of the China Desk in the East German Foreign Ministry and the First Secretary of the Chinese Embassy Qi Huaiyuan with regard to the intended establishment of a Chinese trade representation in West Berlin. East Berlin is clearly concerned such a step might favor West Germany's alleged goal of winning sovereignty over West Berlin, in violation of the Four Power Agreement. Qi states that he does not understand the East German position, and that the activities of Chinese diplomats in West Berlin are in accordance with international law. He rejects the notion that these relations might conceivably harm the interests of East Germany.
