Upper Mongols
The Upper Mongols, also known as the Köke Nuur Mongols or Qinghai Mongols, are ethnic Mongol people of Oirat and Khalkha origin who settled around the Qinghai Lake in so-called Upper Mongolia (present-day Qinghai). As part of the Khoshut Khanate of Qaidam Basin and the Qinghai Lake, they played a major role in Sino–Mongol–Tibetan politics during the 17th and 18th centuries.
