Soviet–Finnish Non-Aggression Pact

The pact was unilaterally renounced by the Soviet Union in 1939 after having committed a deception operation in Mainila in which it shelled its own village and blamed Finland.

[2] The Soviet Union had started negotiations regarding non-aggression agreements with its neighbouring European countries during the Japanese invasion of Manchuria in order to secure its borders.

The pact was signed by A.S. Yrjö-Koskinen and ambassador Ivan Maiski on 22 January 1932 at the Finnish Ministry of Foreign Affairs in Helsinki.

It was ratified by the Parliament of Finland in July 1932, only after the representatives of Estonia, Latvia, and Lithuania had signed their own pacts with the Soviet Union.

The Soviet Union proposed a ten-year period of validity of the pact in the spring of 1934, and wanted Finland, Estonia, Latvia, and Lithuania to give a joint answer for it.
