"As part of the international Open Skies Treaty, the Russian inspection team plans to carry out an observation flight on the Russian An-30B over the territory of the Republic of Poland. An observation flight will be carried out in the period from August 29 to September 2, 2016 from the Open Skies airfield Warsaw with a maximum range of up to 1,400 kilometers (870 miles)," Ryzhkov said.
Under the same treaty, the Danish mission will conduct an observation flight over Russia on the Ukrainian observation aircraft AN-30B from the Kubinka airport during this period.
The Treaty on Open Skies was signed in March 1992 and became one of the major confidence-building measures in Europe after the Cold War. It entered into force on January 1, 2002, and currently has 34 states parties, including Russia and most NATO members.
