The US announced its withdrawal from the airspace surveillance treaty signed with 34 countries, six months after Trump accused Russia of repeatedly violating the agreement.

"The United States exercised its right under paragraph 2, Article 15 of the Open Sky Treaty on May 22, foretelling all the countries concerned of its decision to withdraw from the agreement. Six months have passed,

The Open Sky Treaty signed by the US, Russia and several European countries in 1992, entered into force in 2002, aims to promote transparency in military operations.

The agreement gives US allies and partners access to high-definition aerial data, even if they do not have a network of modern reconnaissance satellites.

The decision to withdraw from the treaty was made by US President Donald Trump after months of review, in which Washington accused Moscow of repeatedly violating the agreement, such as preventing U.S. flights over Georgia airspace and Russia's Kaliningrad territory.

Russian Deputy Foreign Minister Alexander Grushko once said the country did not violate the Open Sky Treaty and "there is nothing to prevent dialogue from solving technical problems that the US side calls an act of violation of the agreement".

NATO members and some Eastern European countries have repeatedly urged the US to maintain the agreement on fear that Russia will withdraw from the treaty in response, undermining security in the region.
