Ram Khamhaeng
By 1298, Wareru felt strong enough that he sent a diplomatic mission to Yuan China to receive recognition directly from the Mongol Emperor. It was a bold gesture as his nominal overlord Ram Khamhaeng himself was a Mongol vassal. The Martaban mission passed through Pagan, where they were briefly arrested in March–April. By then, King Kyawswa of Pagan had been deposed by the three generals from Myinsaing. At any rate, the Martaban mission eventually made it to the emperor's court, and received the emperor's recognition in June/July 1298. The Mongols knew that Wareru was then a vassal of Ram Khamhaeng, and recognized Wareru anyway because they did not want a strong state to emerge in Southeast Asia, even of Tais.
