Having discredited and deposed the Sixth Dalai Lama, whom he considered an impostor, and having removed the regent, Lhazang Khan pressed the Lhasa Gelugpa lamas to endorse a new Dalai Lama in Tsangyang Gyatso's place as the true incarnation of the Fifth. They eventually nominated one Pekar Dzinpa, a monk but also rumored to be Lhazang's son, and Lhazang had him installed as the 'real' Sixth Dalai Lama, endorsed by the Panchen Lama and named Yeshe Gyatso in 1707. This choice was in no way accepted by the Tibetan people, however, nor by Lhazang's princely Mongol rivals in Kokonor who resented his usurpation of the Khoshut Tibetan throne as well as his meddling in Tibetan affairs. The Kangxi Emperor concurred with them, after sending investigators, initially declining to recognize Yeshe Gyatso. He did recognize him in 1710, however, after sending a Qing official party to assist Lhazang in 'restoring order'; these were the first Chinese representatives of any sort to officiate in Tibet. At the same time, while this puppet 'Dalai Lama' had no political power, the Kangxi Emperor secured from Lhazang Khan in return for this support the promise of regular payments of tribute; this was the first time tribute had been paid to the Manchu by the Mongols in Tibet and the first overt acknowledgment of Qing supremacy over Mongol rule in Tibet.
