After the Dzungar conquest, Khangchenné stayed in Ngari and began to interrupt the lines of communication between the Dzungars stationed in Tibet and their home base in Dzungaria. In 1719 he successfully attacked a troop of mounted Dzungar warriors who were about to bring some of Lhabzang Khan's old officers to Dzungaria. Together with the nobleman Pholhané he organized military resistance against the Dzungar. After almost three years, the unpopular Dzungar rule came to an end through a 1720 expedition launched by the Qing Kangxi Emperor. The puppet regent Tagtsepa was executed, the 7th Dalai Lama was brought to Lhasa, and a provisional government was formed by the occupants. Thanks to his great services against the Dzungars, Khangchenné was appointed head of a Tibetan cabinet or Kashag in 1721 on the orders of Kangxi. He thereby kept his own basis of power in Ngari. The old office of "desi" (regent) was abolished as it gathered too much power in one hand. Instead Khangchenné received the titles "Dai-ching Batur" and chairman of the cabinet. He was granted the Yardrokling estate for his personal support.
