The Sinologist Edwin G. Pulleyblank has suggested that the Yuezhi, the Wusun, the Dayuan, the Kangju and the people of Yanqi, could have been Tocharian-speaking. Of these the Yuezhi are generally held to have been Tocharians. The Yuezhi were originally settled in the arid grasslands of the eastern Tarim Basin area, in what is today Xinjiang and western Gansu, in China.
