Though the Yuan dynasty, unlike the western khanates, never converted to Islam, the Mongol rulers of the dynasty elevated the status of foreigners of all religions from west Asia like Muslims, Jews, and Christians versus the Han, Khitan, and Jurchen, and placed many foreigners such as Muslim Persians and Arabs, Jews, Nestorian Christians, Tibetan Buddhist Lamas, and Buddhist Turpan Uyghurs from Central and West Asia in high-ranking posts instead of native Confucian scholars. The state encouraged Muslim immigration, as Arab, Persian and Turkic immigration into China accelerated during this period. The Mongol emperors brought hundreds of thousands of Muslims with them from Persia to help administer the country.
