evidence: With the fall of the Qing dynasty in 1911, Mongolia under the Bogd Khaan declared its independence. But the newly established Republic of China considered Mongolia to be part of its own territory. Yuan Shikai, the President of the Republic of China, considered the new republic to be the successor of the Qing. Bogd Khaan said that both Mongolia and China had been administered by the Manchu during the Qing, and after the fall of the Qing dynasty in 1911, the contract of Mongolian submission to the Manchu had become invalid.[32] [...] After the establishment of the People's Republic of China, both countries confirmed their mutual recognition on 6 October 1949. However, the Republic of China used its Security Council veto in 1955, to stop the admission of the Mongolian People's Republic to the United Nations on the grounds it recognized all of Mongolia —including Outer Mongolia— as part of China. This was the only time the Republic of China ever used its veto. Hence, and because of the repeated threats to veto by the ROC, Mongolia did not join the UN until 1961 when the Soviet Union agreed to lift its veto on the admission of Mauritania (and any other newly independent African state), in return for the admission of Mongolia. Faced with pressure from nearly all the other African countries, the ROC relented under protest. Mongolia and Mauritania were both admitted to the UN on 27 October 1961.[41][42][43] (see China and the United Nations)
