Answer
Joseph Stalin personally orchestrated Khorloogiin Choibalsan's rise to power in the 1930s, as he was interested in expanding Soviet influence in Mongolia. Choibalsan was a Mongolian communist who had been exiled to the Soviet Union in the early 1920s, where he came to know Stalin. Stalin was impressed by Choibalsan's political skills and ambition, and he helped Choibalsan to return to Mongolia and take power.
