The [[Soviet–Japanese border conflicts]], also known as the "Soviet–Japanese Border War" or the first "Soviet–Japanese War", was a series of minor and major conflicts fought between the Soviet Union and the [[Empire of Japan]] from 1932 to 1939. Japan's expansion into [[Northeast China]] created a common border between Japanese controlled areas and the [[Soviet Far East]] and [[Mongolia]]. The Soviets and Japanese, including their respective [[client state]]s of the [[Mongolian People's Republic]] and [[Manchukuo]], disputed the boundaries and accused the other side of border violations. This resulted in a series of escalating border skirmishes and [[punitive expedition]]s, including the 1938 [[Battle of Lake Khasan]], and culminated in the Red Army finally achieving a Soviet-Mongolian victory over Japan and Manchukuo at the [[Battles of Khalkhin Gol]] in September 1939. The Soviet Union and Japan agreed to a ceasefire. Later the two sides signed the [[Soviet–Japanese Neutrality Pact]] on 13 April 1941, which resolved the dispute and returned the borders to ''[[status quo ante bellum]]''.<ref>{{cite web|title=Soviet–Japanese Neutrality Pact April 13, 1941: Declaration Regarding Mongolia|url=http://avalon.law.yale.edu/wwii/s2.asp|quote=In conformity with the spirit of the Pact on neutrality concluded on April 13, 1941, between the U.S.S.R. and Japan, the Government of the U.S.S.R. and the Government of Japan, in the interest of insuring peaceful and friendly relations between the two countries, solemnly declare that the U.S.S.R. pledges to respect the territorial integrity and inviolability of Manchoukuo and Japan pledges to respect the territorial integrity and inviolability of the Mongolian People's Republic.|publisher=Yale Law School|access-date=23 December 2014|archive-date=19 August 2017|archive-url=https://web.archive.org/web/20170819141330/http://avalon.law.yale.edu/wwii/s2.asp|url-status=live}}</ref>
