Chahar Province
After establishing a ceremonial Mengjiang-Manchukuo alliance in May 1935, Puyi honoured Demchugdongrub with the title of "Martial Virtue Prince of the First Rank" ( "Wǔdé Qīnwáng"). In June 1935 the North Chahar Incident and the resulting Chin–Doihara Agreement substantially affected events in Chahar Province.
