パクパ
The bureau was set up in Khanbaliq (modern Beijing) and was named after the Xuanzheng Hall where Tibetan envoys were received in the Tang dynasty. In the Yuan dynasty, Tibet was managed by the Bureau of Buddhist and Tibetan Affairs, separate from the other Yuan provinces such as those established in the former territories of the Song dynasty. While no modern equivalents remain, the political functions of the Bureau of Buddhist and Tibetan Affairs might have been analogous to the India Office in London during the British Raj. Besides holding the title of Imperial Preceptor or Dishi, Drogön Chögyal Phagpa, the fifth leader of the Sakya school of Tibetan Buddhism, was concurrently named the director of the Bureau of Buddhist and Tibetan Affairs.
