徐树铮
In October 1919, China's new Northwest Frontier Commissioner Xu Shuzheng arrived in Urga with a military escort and demanded that the "Sixty-Four Articles" be renegotiated. He submitted a much tougher set of conditions, the "Eight Articles," calling for the express declaration of Chinese sovereignty over Mongolia, an increase in Mongolia's population (presumably through Chinese colonization), and the promotion of commerce, industry, and agriculture. Xu installed Badamdorj, who represented reactionary lamas and was considered to be more pliable to Chinese demands, as prime minister. Xu threatened to exile the Bodg Khan if Badamdorj and others did not sign the "Eight Articles" wherein the Mongolian government "voluntarily" relinquished the country's autonomy to Chinese administration. Other national leaders including Foreign Minister Balingiin Tserendorj and the Bogd Khan himself soon followed suit. Badamdorj remained prime minister for only a short period thereafter, until January 1920.
