However, he would join the pro-Japanese Mongol United Autonomous Government after its establishment in 1937. He took up the position of deputy head of Yeke-juu league under that government as well in February 1938. Previously a close friend of local warlord Fu Zuoyi, he asked Prince Demchugdongrub to send troops to help him break out of the control of Fu Zuoyi and join Demchugdongrub's autonomy movement. Overlooking Altanochir's former friendship with the warlord and his questionable loyalty to the Mongol autonomy movement, Demchugdongrub agreed to send one cavalry brigade in the spring of 1938 to assist him. After the formation of the Mengjiang United Autonomous Government in October 1939, Altanochir became a member of the Mongol Revival Committee (興蒙委員會) and general commander of the Ordos Army (鄂爾多斯挺進軍). In 1947 after the war had ended, he returned to his position as deputy head of Yeke-juu league. In early 1949 he was named a member of the Mongol Autonomous Preparatory Committee (蒙古自治籌備委員會) at Dingyuanying (定遠營; today Bayan Hot, Alxa League); he died there on 16 April 1949.
