Nima-odsor[a] (1894 – 23 January 1936), also known under the Chinese name of Ni Kuan-chou (Chinese: 尼冠洲)[1] was a Mongol politician active in the Republic of China who was shot to death by Japanese assassins on an intercity bus ride.
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.[3] The Japanese denied any connection and claimed it had been done by Chinese agents.[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.[3] Later scholarly sources conclude that the assassination was a Japanese plot in response to Nima-odsor's Mongol nationalism and opposition to Japanese expansionism.[4] In the aftermath, Demchugdongrub, who had been working with the Japanese, stated that he knew in advance of a (failed) Japanese plot to assassinate Ünenbayan, but the assassination of Nima-odsor came as a complete surprise to him, because he thought the latter would be protected by Jodbajab.[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.[4]
