Russia’s withdrawal from the Open Skies Treaty will have a negative impact on the entire global arms control architecture, EU Foreign Policy chief Josep Borrel said in a statement.

“Russia’s announcement of its withdrawal from the Open Skies Treaty is regrettable and will have a detrimental impact on the global arms control architecture,” the document says.

The EU stressed that it will “study the consequences of this decision (of Russia) for its own security and the security of its partners.” “By providing transparency and predictability, the Open Skies Treaty contributes to vital confidence-building. The return of all to their obligations under the Treaty will strengthen European and global security and stability,” Borrel said in a statement.
