[1][4] In January 1936, Nima-odsor, Ünenbayan, Serengdongrub, and Demchugdongrub went to Zhangbei for a meeting with Jodbajab.
[5] In that meeting, they discussed Jodbajab's deployment of cavalry police in six counties in northern Chahar Province (demilitarised by the Chin–Doihara Agreement in the wake of the North Chahar Incident) in response to Manchukuo troops' occupation of the area under Li Shouxin the previous month.
[3] After the meeting ended, on 23 January Nima-odsor took a bus to return to Kalgan; gunmen in civilian clothes stopped the bus, boarded it, identified Nima-odsor, shot him at point blank range, and then fled without harming any other passengers.
[6] Newspaper reports at the time suggested Nima-odsor thought that Jodbajab had exceeded his authority and that there might be some conflict between the two.
[7] The most notable consequence of Nima-odsor's assassination was that his friend Jodbajab was intimidated into further cooperation with the Japanese, and joined Demchugdongrub's Mongol Military Government soon after.
