On this day, 98 years ago, on December 14, 1927 (November 21, 1927, the National Government broke off diplomatic relations with the Soviet Union. Soviet nationals living in various places were expelled from the country. On December 14, 1927, the Nanjing National Government issued an order to sever diplomatic relations with the Soviet Union, claiming that "the Guangdong Incident occurred on the 11th of this month. The reason for the incident was that the Communist Party and the Soviet Union Consulate and its state-owned commercial institutions were the place for manipulation and instructions." Other provinces are also worried about an outbreak. For the sake of public security, all Soviet consuls stationed in all provinces should be revoked, and all Soviet state-owned agencies in all provinces should be ordered to cease business. On the 15th, Foreign Minister Wu Chaoshu went to the Consulate General of the Soviet Union in Shanghai and handed over a letter to cut off the country's transportation and restricted the Soviet Consul to leave the country within one week. On the same day, the Ministry of Foreign Affairs drew up three measures for breaking off diplomatic relations between China and the Soviet Union: the consul was revoked, and the consulate staff would leave the country within a time limit; all Soviet state-owned commercial establishments would be ordered to suspend business; and a detailed survey of the total number of Soviet nationals, all Soviet nationals should obtain an alien license. Subsequently, cases of searches and occupation of Soviet consular premises, surveillance, arrest and killing of Soviet diplomats and Soviet nationals occurred one after another. More than 5700 people were killed on the horrific streets of Guangzhou
