In the time of Emperor Gao and Empress Wuzetian of the Tang dynasty, Tu-bo annihilated the Tuyuhun, threatened Longshi and Hexi of the Tang empire and formed an alliance with the Western Turks to fight the Tang for control of Anxi. There were battles as well as negotiations between the two sides. In 709, the Tang married a princess from the imperial family to Tsenpo Kride Zukzain. But there were still conflicts between the two governments. After the An Lushan Rebellion, the Tang recalled some of its armies from the frontiers so Tu-bo occupied Longyou and Guanxi when Tang military power was weak at these places. In 763, Tu-bo attacked Chang’an. Hexi, Anxi and Beiting were completely cut off from the Tang central power and fell into enemy hands. Nanzhao located to the southwest of the Tang also submitted to Tu-bo.
