The Tannu Uriankhai lands, according to the Imperial Institutes of the Tsing Dynasty, were under the control of the Tartar General of Uliasutai, the Sain Noin Aimak, the Jasaktu Khan Aimak and the Jetsun Dampa Hutkhta, and divided into forty-eight somons (tsoling). Geographically, according to the same authority, Tannu Uriankhai is bounded on the north by Russia, east by Tushetu Khan Aimak, west by the various aimks of Kobdo, and south by Jasaktu Khan Aimak. By a Joint Demarcation Commission in 1868 the Russo Chinese boundary in respect to Uriankhai was denmited and eight wooden boundary posts were erected to mark their respective frontiers.
In 1910, however, a Russian officer removed and burnt the boundary post at Chapuchi Yalodapa. The matter was taken up by the then Waiwupu with the Russian Minister. He replied to the effect that the limits of Uriankhai were an unsettled question and the Russian Government would not entertain the Chinese idea of taking independent steps to remark the boundary or to replace the post and expressed dissatisfaction with the work of the Joint Demarcation Commission of 1868, a dissatisfaction which would seem to be somewhat tardily expressed, to say the least. The case was temporarily dropped on account of the secession of Uliasutai from China in the following year.
While Uriankhai forms part of Autonomous Outer Mongolia, yet since Outer Mongolia is under China's suzerainty, and its territory is expressly recognized to form part of that of China, China cannot look on with indifference to any possible cession of territory by Outer Mongolia to Russia. Article 3 of the Kiakhta Agreement, 1915, prohibiting Outer Mongolia from concluding treaties with foreign powers respecting political and territorial question acknowledges China's right to negotiate and make such treaties. It is the firm intention of the Chinese Government to maintain its territorial integrity basing its case on historical records, on treaty rights and finally on the principle of nationality. It is notorious that the Mongols will be extremely unwilling to see Uriankhai incorporated into the Russian Empire. While Russia is spending countless lives and incalculable treasure in fighting for the sacred principle of nationality in Europe, we cannot believe
