Mongol unification dream persists
9 September 1945. Although they understand the implication of the Sino–Soviet Treaty is that the unification of Outer and Inner Mongolia is not acceptable, the leaders of eastern Inner Mongolia and members of the Inner Mongolian People’s Revolutionary Party do not want to give up hope. They send a letter to Choibalsan, expressing their wishes for unification with the MPR and ask him to pass on their request to Stalin. On the following day, similar letters are sent to the Soviet Army Headquarters.
