 Mongols have at times advocated for the historical Oirat Dzungar Mongol area of Dzungaria in northern Xinjiang to be annexed to the Mongolian state in the name of Pan-Mongolism.In 1918 the part Buryat Mongol Transbaikalian Cossack Ataman Grigory Semyonov declared a "Great Mongol State" and had designs to unify the Oirat Mongol lands, portions of Xinjiang, Transbaikal, Inner Mongolia, Outer Mongolia, Tannu Uriankhai, Khovd, Hu-lun-pei-erh and Tibet into one.The Buryat Mongol Agvan Dorzhiev tried advocating for Oirat Mongol areas like Tarbagatai, Ili, and Altai to get added to the Outer Mongolian state.
