In March 1934, Jodubjab was appointed a member of the Nanjing government's newly established Mongolian Local Autonomous Political Committee, along with Kesingge, Serengdongrub, Ünenbayan, and Nima-odsor of the Kuomintang, and various league and banner nobility such as Altanochir, Darijaya, and Gorjorjab (郭尔卓尔扎布). However, in early 1936, Nima-odsor, who was Jodubjab's close friend and advisor, was assassinated by the Japanese for his Mongol nationalism and opposition to Japanese expansionism. In response, Jodubajab, intimidated, began to collaborate with Japan's territorial designs on Inner Mongolia, sparking the ire of Mongol nationalists. In his position as commander of the Mongol militia, he endorsed Prince Demchigdongrob's telegram announcing the establishment of the Mengjiang government. In February of that year, he and Li Shouxin seized control of the postal administration in six districts of eastern Chahar Province. In November of that year, he participated in the Suiyuan Campaign. In 1937 he was appointed one of two deputy commanders of the Mongol Pao An Tui (蒙古保安隊) along with Pao Yueh-ching (包悦卿).
