Treaty on Open Skies Review Conference, June 7-9, Vienna, Austria
The Treaty on Open Skies is one of the most wide-ranging international arms control efforts to date to promote openness and transparency in military forces and activities. As such, the Treaty provides a key mechanism in support of U.S. Euro-Atlantic security objectives as recently outlined by Vice President Biden and Secretary Clinton. The Treaty on Open Skies established a regime for unarmed aerial observation flights over the territories of its signatories. The Treaty is designed to enhance mutual understanding and confidence by giving all participants, regardless of size, a direct role in gathering and sharing information through aerial imaging of military forces and activities of concern to them.
The Treaty requires that a Review Conference be held every five years. The first conference to review the treaty was held in 2005.
