Mongolie-Extérieure
While the administrative Outer Mongolia only consisted of the four Khalkha aimags (Setsen Khan Aimag, Tüsheet Khan Aimag, Sain Noyon Khan Aimag, and Zasagt Khan Aimag), in the late Qing period "Outer Mongolia" was also used to refer to Khalkha plus Oirat areas Khovd and the directly-ruled Tannu Uriankhai.
