Ethnic Mongolian guerilla units were created by the Kuomintang Nationalists to fight against the Japanese during the war in the late 30s and early 40s. These Mongol militias were created by the Ejine and Alashaa based commissioner's offices created by the Kuomintang.[26][27] Prince Demchugdongrob's Mongols were targeted by Kuomintang Mongols to defect to the Republic of China. The Nationalists recruited 1,700 ethnic minority fighters in Inner Mongolia and created war zones in the Tumet Banner, Ulanchab League, and Ordos Yekejuu League.[26][28]
