What world leader signed a secret nonaggression pact with germany

The Neutrality Pact between Nazi Germany and the Soviet Union was signed in Moscow on August 23, 1939. The clause of this pact implied a written guarantee of non-attack of any of the parties to the other, and that no government would unite with someone against the other side of the pact.
