 However, in the tripartite Kyakhta agreement of 1915 (between Russia, China, and Mongolia), Mongolia's status was changed to mere autonomy.In 1919, Mongolian nobles, over the opposition of the Bogd Khan, agreed with the Chinese resident Chen Yi on a settlement of the "Mongolian question" along Qing-era lines, but before this settlement could be put into effect, Khüree was occupied by the troops of Chinese warlord Xu Shuzheng, who forced the Mongolian nobles and clergy to renounce autonomy completely.The city changed hands twice in 1921.
