Seventy-nine years ago today, on January 3, 1946 (December 1, 1945 in the lunar calendar), the Nationalist government recognized the independence of Outer Mongolia. On January 3, 1946, the Nationalist government issued a proclamation recognizing the independence of Outer Mongolia (English: OuterMongolia, Mongolia). On August 14, 1945, Foreign Minister Wang Shijie of the Nationalist government and Foreign Minister Molotov of the Soviet government signed the Sino-Soviet Treaty of Friendship and Alliance in Moscow. As a subsidiary agreement, the two foreign ministers also exchanged the "Sino-Soviet Notes on the Question of Outer Mongolia". Its main content is: Because Outer Mongolian citizens have repeatedly expressed their desire for independence, the Chinese government declares that after the defeat of Japan, if the referendum of Outer Mongolia confirms this (independence) desire, the Chinese government shall recognize the independence of Outer Mongolia and use the current border as the national border. According to the treaty, a referendum was held in Outer Mongolia on October 20, 1945, and the Chinese National Government sent representatives to visit. On January 5, the joint meeting of the Council of Ministers of the Mongolian People's Republic, the Grand National Assembly, and the Central Committee of the People's Revolutionary Party officially declared Mongolia's independence. Outer Mongolia Established Sukh Bator 1919 Sukh Bator and Chobashan, who were herdsmen, sought the help of the Communist International to establish an independent Mongolian state. In 1920, with the help of Lenin, Sukh Bator and Chobashan formed the Mongolian Communist Party, the Mongolian People's Party. On July 9, 1920, Duan Chirui stepped down, and Xu Shuzheng led his army back to the mainland. He was wanted and fled to the Japanese embassy. Coulomb left only part of his troops behind. On February 11, 1921, during the Soviet Civil War, White Russian troops invaded Kulun with the support of the Japanese Kwantung Army. The Chinese garrison withdrew from Kulun, some returned to the mainland, and some were transferred to Merchant City under the leadership of Gao Zaitian, ready to fight again. On March 18, the Mongolian People's Party army captured Merchant City with the support of the Soviet Red Army and drove out the Chinese garrison. Due to the fact that China was on the eve of the first direct war, the warlords of various factions had no time to separate themselves and had to sit back and watch Mongolia become independent with the help of the Soviet Union. The Soviet Red Army was invited to enter Mongolia on May 25 with the support of the Mongolian People's Party army. On July 6, 1921, Kulun was captured. On July 11, 1921, Outer Mongolia established a pro-Soviet constitutional monarchy. On November 25, Outer Mongolia established a "people's revolutionary regime" and concluded the "Treaty of Reconciliation between Su and Mongolia" with the Soviet Union in 1922. The various factions of the Northern warlords, such as Duan Qirui, Zhang Zuolin, Cao Kun, Wu Peifu, etc., were too busy fighting each other to do anything about it. As a form of diplomacy, the Xu Shichang government in Beijing issued a statement condemning Outer Mongolia's attempt to divide the Republic of China and not recognizing Outer Mongolia's independence. Soon after, the Mongolian monarch Dzebuzun Danba Living Buddha died suddenly. With the support and action of the Soviet Third International and the Mongolian People's Party, the Mongolian government announced on November 26, 1924 that it would abolish the constitutional monarchy and establish the Mongolian People's Republic. The capital was set at Kurun, and the city was renamed Ulaanbaatar, with 1911 as the era of independence. But China and the major governments of the United Kingdom and the United States at that time did not recognize it Outer Mongolia has repeatedly proposed to return to China. The Mongolian State Great Hural Conference on December 30, 2004 specifically discussed the establishment of a Mongolia-China alliance and the incorporation of Mongolia into China. During the discussion, the members of the Gobi Province proposed to incorporate Mongolia into China and establish a special administrative region of China similar to Hong Kong and Macau, so that Mongolia could eventually return to the motherland. As early as 1995, 2000, and 2002, some members of the Mongolian State Great Hural have repeatedly proposed Mongolia's return to China. However, due to resistance, the proposal has not been discussed. In recent years, the Mongolian government has come under increasing pressure due to economic difficulties. The prosperous Mongolian life in China's Erlian and other places has created a strong attraction for herders. Including many upper-class figures, they are increasingly attracted by China's economic development, especially the relative prosperity and prosperity of Inner Mongolia. But on the other hand, it will be very difficult for China to regain Outer Mongolia on the political map. First, there is still a lot of resistance within Outer Mongolia to the return to China, and there is a certain gap between the merger form conceived by the return faction and China's wishes. Second, the international resistance, including the United States, Japan, and especially Russia, will be very fierce. After all, China still needs Russia in terms of international strategy and national defense development. Third, the reaction of the Mongolian people in China to this matter cannot be ignored. It should be pointed out that the loyalty of the Mongolian people in China to the country is beyond doubt. The so-called Mongolian independence is purely a YY of a very small number of Mongolian intellectuals and overseas anti-China forces. Despite this, many Mongolian people in Inner Mongolia do not want to see an independent Mongolian state disappear completely. I think this sentiment should be understandable. Rashly recovering Outer Mongolia may cause resistance among the people of Inner Mongolia. The Mongolian National Assembly has proposed to return to China 43 times. Due to various reasons, China has not had any positive comments and responses so far.
