 His attempts to monopolize power among the Oirat tribes, however, was only partially successful.The dissension and skirmishes, for example, compelled Güshi Khan and his brother, Kundelung Ubasha, to move a substantial part of the Khoshut-Oirat tribe from the Lake Zaisan area to the area around Qinghai Lake - what the Chinese called Qinghai and the Tibetans called Amdo - in 1636, where they soon would establish the Khoshut Khanate and transform Tibet into a Qing protectorate.But the unity Erdeni Batur created among the remaining Oirat tribes, viz., Choros, Dörbet and Khoit tribes, further strengthened his power and his resolve to establish the Dzungar Khanate as the preeminent power in Central Asia.
