The Japanese expansion in Northeast China created a common border between the Japanese occupied ground and the Soviet Far East. This led to growing tensions with the Soviet Union, with both sides often violating the border and accusing each other of border violations. The Soviets and Japanese, including their respective client states of Mongolia and Manchukuo, fought in a series of escalating small border skirmishes and punitive expeditions from 1935 until Soviet-Mongolian victory over the Japanese in the Battles of Khalkhin Gol in 1939 which resolved the dispute and returned the borders to status quo ante bellum.
The Soviet–Japanese border conflicts heavily contributed to the signing of the Soviet–Japanese Neutrality Pact in 1941.
