The parties to the agreement pledged themselves to provide support and assistance to each other in the war against Hitlerite Germany and not to negotiate or conclude, except by mutual consent, any armistice or peace treaty.

The protocol, signed the same day, stipulated that the agreement would come into force as soon as it was signed and that it would not require ratification.
