The title Malik al-Mashriq wa'l-Ṣīn was bestowed by the 'Abbāsid Caliph upon the Tamghaj Khan, the Samarqand Khaqan Yūsuf b. Ḥasan and after that coins and literature had the title Tamghaj Khan appear on them and were continued to be used by the Qarakhanids and the Transoxania-based Western Qarakhanids and some Eastern Qarakhanid monarchs, so therefore the Kara-Khitan (Western Liao)'s usage of Chinese things such as Chinese coins, the Chinese writing system, tablets, seals, Chinese art products like porcelein, mirrors, jade and other Chinese customs were designed to appearl to the local Central Asian Muslim population since the Muslims in the area regarded Central Asia as former Chinese territories and viewed links with China as prestigious and Western Liao's rule over Muslim Central Asia caused the view that Central Asia was a Chinese territory to reinforce upon the Muslims; "Turkestan" and Chīn (China) were identified with each other by Fakhr al-Dīn Mubārak Shāh with China being identified as the country where the cities of Balāsāghūn and Kashghar were located.
