In addition to Dawlat Shah, there were two Muslims, Ubaidullah and Bayanchar, who served as managers of governmental affairs in the Secretariat. Mahumud Shah and Hasan Khoja managed the Bureau of Military Affairs. In contrast with the Muslims, Chinese officials exerted little influence on the administration. The high point of the Mongol partner-merchants' operations came under Yesün Temür, whose administration exempted Christians and Muslims from any corvee payments and guaranteed huge payments promised by the Mongolian nobility in return for luxury goods (тансаг).
