STATES PARTIES TO THE OPEN SKIES TREATY

The Treaty on Open Skies was signed in Helsinki, Finland, on March 24, 1992. Twenty-seven states have signed the Treaty; of whom 22 have ratified it. The Treaty on Open Skies represents the broadest and most flexible effort to date to promote openness of military forces and activities from Vancouver, east to Vladivostock.

The Open Skies Treaty will enter into force sixty days after the deposit of 20 instruments of ratification, including those of the depositories (Canada and Hungary), and of States Parties whose individual allocation of passive quotas is eight or more. Ratification by Russia, Belarus and Ukraine is required for the Treaty to enter into force (expected in 1996).
