Tannu Uriankhai (as well as Altai and Altainor Uriankhai) occupied a unique position in the Qing dynasty's frontier administration system. If Qing statutes rigorously defined procedures to be followed by the nobles of Outer and Inner Mongolia, Zungaria, and Qinghai for rendering tribute, receiving government stipends, and participating in imperial audiences, they are silent regarding Tannu Uriankhai. After the demarcation of the Sino-Russian border by the Treaty of Kyakhta (1727), the Qing inexplicably placed border guards ("yurt pickets," Mongolian: "ger kharuul") south of the Tannu-ola Mountains separating Tannu Uriankai from Outer Mongolia, not along the Sayan Mountains separating the region from Russia. (This fact was used by 19th-century Russian polemicists, and later Soviet writers, to prove that Tuva had historically been "disputed" territory between Russia and China.) The Qing military governor at Uliastiai, on his triennial inspection tours of the 24 pickets under his direct supervision, never crossed the Tannu-ola mountains to visit Uriankhai. When problems occurred meriting official attention, the military governor would send a Mongol from his staff rather than attend to the matter himself.
