On 114 years ago today, August 15, 1911 (June 21, the 1911 lunar calendar), Russia supported the independence of Outer Mongolia. On August 15, 1911, a Mongolian delegation arrived in Petersburg and demanded the "protection" of the tsar on behalf of the princes of all Mongolia. The tsar "treated him as a guest of the court." Tsarist Russian ministers assured them of their support for the "independence" of Outer Mongolia. On the 17th, Tsarist Prime Minister presided over a special meeting on the Far East issue and believed that "China plans to implement a new policy in Mongolia,... Especially in areas close to our territory, the presence of a large number of China troops cannot but worry us." Therefore, the Mongolian issue "is of great significance, and it is fully in my country's interests to support the Mongolian people's desire to oppose the above-mentioned China government plan." On the 28th, Tsarist Russia's Minister to China Kosowitz immediately wrote a note to the Ministry of Foreign Affairs of the Qing Dynasty, claiming that the Qing Dynasty's policy on outer Mongolia "shows a dangerous phenomenon in the diplomatic relations between the two countries, making Russia unable to provide necessary protection on the border" and that "Kulun and my country are close to the border. China should consider the friendship between China and Russia and suspend the last new policy immediately to relieve people's doubts and fears. Otherwise, Russia cannot ignore it." At the same time, Tsarist Russia sent more than 800 infantry and cavalry troops south from Chaktu to Kurun, forcing the Qing government to suspend the "New Deal". At the beginning of 1911, the Qing government believed that in order to consolidate the border, it was necessary to implement the "New Deal" to foreign Mongolia. Therefore, in March, it sent more than three ministers to serve in Kulun and began to implement the "New Deal". About 20 agencies were set up to handle military, taxation, police, constitutional government, health, diplomacy, trade, industry, education, and immigration and land reclamation matters, arousing doubts among Mongolian princes. Tsarist Russia secretly instigated the "independence" of the Living Buddha and the princes of Outer Mongolia.
