SINO-SOVIET WAR
YEARS: 1929-1929 | DEATHS: 3200
The Sino-Soviet conflict of 1929 (1929年 中東路事件) was a minor armed conflict between the Soviet Union and the Republic of China over the Manchurian Chinese Eastern Railway.
When the Chinese seized the Manchurian Chinese Eastern Railway in 1929, swift Soviet military intervention quickly put an end to the crisis and forced the Chinese to accept restoration of joint Soviet-Chinese administration of the railway.
