When the Mongol envoys led by Qidai Tuoyin showed up , the Pagan court led by Chief Minister Ananda Pyissi was well aware of the military power of the Mongols and advised King Narathihapate to use diplomacy . The king was furious at the demand and kept the Mongol envoys waiting for weeks . The court finally devised a compromise : the envoys were sent back without ever seeing the king . Accompanying them was a Burmese envoy who carried a letter expressing friendly sentiments and the Burmese king 's wish to one day worship a Buddha tooth at Beijing . The king then promptly ordered an expedition , which retook the rebellious borderland regions in April 1272 . The rebel leader A @-@ Pi ( အပိ ) was brought back to Pagan . Dali relayed the news to Beijing but did not carry out any military action .
