The below Map Image provides a quick overview of the Central and East Asian Region focussing on Inner- and Outer Mongolia. Map further includes parts of the Tuva Republic, Irkutsk Oblast, the Trans-Baikal Region, the path of the Trans-Siberian Railway and the Russian Primosky Krai Maritime Province. Notable fringe elements are the Korean Peninsula i/t East and parts of East Turkestan (Xinjiang) and the Kokonor Region (now Qinghai) of the Nation of Tibet.
Map was produced by R. Chapman Andrews for the Museum of Natural History and shows the route of his expeditions between 1922 and 1930 AD.

Although the Manchu ruled Qing Dynasty Empire had previously conquered large parts of East Asia, including much of Korea, parts of current day Siberia, most of Mongolia, East Turkestan, Kyrgyz, Kazakh and other tribal lands while subjecting Tibet, remote and inaccessible behind its mountainous walls, to a subjugary role. At the turn of the 20th Century the outer regions of the Qing Empire have been eroded away, much of the north and west increasingly under Russian control while in the south and along the coast Britons and others had fought their way into the Chinese Realm. Notably, Korea has been annexed by Japan and Tibet is shown as a de facto independent territory. Tibet will be invaded by Britain in 1901 AD and will declare Independence not long there after at the fall of the Manchu Dynasty and the end of Manchu rule over China but also Mongolia and Manchuria in 1911 AD. Other groups such as Mongolians, Kazakhe and Kyrgyz will likewise attempt to reestablish their National independence after the fall of the Manchu Empire.
Historic Map China (Qing) Empire in 1910 AD
An obviously non-Chinese but western-made Map of the Qing Dynasty Chinese Empire in the year 1910 AD, a year in which China's sovereignty has been under threat and siege for over 70 years.
In this Map of 1910 AD, made one year before the abdication of Last Ching Emperor Xuan Tung (a.k.a. Aisin-Gioro Pu Yi) and the final end of China's Feudal History, China is depicted as in its smallest boundaries and definition. Most notably Manchuria, and Inner Mongolia, both territories nominally under Chinese Control and under Chinese Sovereignty are depicted as separate area's.
Other interesting features of the Map and geography of the Time : after the Sino-Japanese war of 1899 AD, both Korea and the Island of Formosa (now Taiwan / ROC) have been annexed by the Japanese Empire.
