In 1935, Demchugdongrub, now the leader of the Mongols of Inner Mongolia, made serious efforts to set up an autonomous Mongolian Government in Chahar and Suiyuan. The Japanese General [[Jirō Minami]], commander of the [[Kwantung Army]], and Colonel [[Seishirō Itagaki]] gave support to the new Inner Mongolian Autonomous Government, which they felt would weaken China and be subject to the influence of Japan. In April 1935 Minami sent Major [[Ryūkichi Tanaka]] and another officer to interview Demchugdongrub with the goal of formalizing Japanese support, but Demchugdongrub did not agree to terms set by the Japanese at that time.

After establishing a ceremonial Mengjiang-[[Manchukuo]] alliance in May 1935, [[Puyi]] honoured Demchugdongrub with the title of ''Martial Virtue Prince of the First Rank'' ({{lang|zh-Hant|武德親王}} ''Wǔdé Qīnwáng''). In June 1935 the [[North Chahar Incident]] and the resulting [[Chin–Doihara Agreement]] substantially affected events in Chahar Province.

The most important provisions of the Chin-Doihara Agreement forced all units of the Chinese 29th Army to be withdrawn from the eastern districts of Chahar province and north of [[Zhangbei County|Changpei]], including the 132nd Division in Changpei. The withdrawal of the 132nd Division effectively ceded control of nearly all of Chahar province in Mengjiang. Peace and order in Chahar was to be entrusted to the Peace Preservation Corps, an organization that was little more than a police force with light arms only.

Also, no Chinese were to be permitted to migrate to or settle in the northern part of Chahar Province, which was largely populated by nomadic Mongols. No activities of the Kuomintang were to be permitted in Chahar Province. All anti-Japanese institutions and official acts in Chahar Province were banned.<ref>[[#Bisson1973|Bisson (1973)]], p. 67</ref><ref>[[#Hsu1937|Hsu (1937)]], p. 21</ref> When General Minami met with Prince Demchugdongrub in August 1935, the Prince promised close cooperation with Japan, and Minami promised financial assistance to the Prince.
