The Khabarovsk Protocol of 1929 is an agreement between the USSR and China on the elimination of the conflict on the CER , signed on December 22, 1929 .
On July 10, 1929, Chinese troops captured the CER , arresting over 200 Soviet road employees, 35 of whom were deported to the USSR, which led to a sharp deterioration in relations between the two countries. On July 17, 1929, the USSR government announced the severance of diplomatic relations with China; in November 1929, the Special Red Banner Far Eastern Army carried out a swift operation to liberate the CER. December 22, 1929 in Khabarovsk, the authorized representative of the Chinese Republic Tsai Yanshen and the authorized representative of the USSR, the NKID agent Simanovsky signed the Khabarovsk Protocol, according to which the status quo was restored to the CER in accordance with the Beijing and Mukden agreements. This event ended the conflict on the CER.
This document restored the situation before the conflict on the CER, preserving the joint management of the railway. The Chinese authorities pledged to disarm the White Guard units in Manchuria and release the arrested Soviet citizens. The agreement provided for the immediate restoration of the USSR consulates in Manchuria and the Chinese consulates in the Russian Far East , as well as the resumption of the activities of Soviet economic organizations that existed in Manchuria before the conflict, and Chinese commercial organizations in the USSR.
According to the Khabarovsk Protocol, the settlement of all controversial issues and the restoration of diplomatic relations between the two countries in full was planned to be resolved at the Soviet-Chinese conference, which was to be held in Moscow in January 1930 .
