Trans-Salween Chinese Shan states (1562–1563)

The king spent the next two years preparing for war against Siam, which he considered his unfinished business. He set up a garrison at Tavoy (Dawei) on 17 June 1562. But he first wanted to bring the trans-Salween Shan states into his fold, probably to get more manpower as well as to secure the rear. The Burmese chronicles states that he was merely responding to a July 1562 rebellion by his cis-Salween Chinese Shan states with support from trans-Salween Shan states. However, as with Manipur, it may just have been a pretext. He sent four 12,000-strong armies, led respectively by Nanda, Thado Dhamma Yaza II, Minkhaung II and Thado Minsaw. The southernmost trans-Salween state of Kengtung submitted prior to the invasion on 16 December 1562. The armies launched a two-pronged invasion of the Taping valley in March/April 1563. The armies faced minimal resistance, and secured the allegiance of the local saophas. Bayinnaung now had at least nominal suzerainty over the Chinese Shan states from the cis-Salween states in the Taping valley to Kenghung (present-day Xishuangbanna Dai Autonomous Prefecture, Yunnan) in the east.
