Buddhism and Taoism was tolerated, and Xuanzang honoured. He suppressed frontier tribes, intervened in Nepal, invaded Korea (unsuccessfully), extended suzerainty over the Sassanids (Persia), defeated the E Turks (630), established protectorates over Annam, Manchuria, Mongolia, and the Tarim (Xinjiang), and united the royal houses of China and Tibet (649).
