MOSCOW -- Russia said Friday that it will withdraw from an international treaty allowing surveillance flights over military facilities after the U.S. exit from the pact, compounding the challenges faced by President-elect Joe Biden's administration.
Russia's Foreign Ministry said in a statement that the U.S. withdrawal from the Open Skies Treaty last year "significantly upended the balance of interests of signatory states," adding that Moscow's proposals to keep the treaty alive after the U.S. exit have been cold-shouldered by Washington's allies.
The ministry said Russia is now launching the relevant procedures to withdraw from the pact "due to the lack of progress in removing the obstacles for the treaty's functioning in the new conditions." The Russian parliament, which ratified the treaty in 2001, will now have to vote to leave it.
The treaty was intended to build trust between Russia and the West by allowing the accord's more than three dozen signatories to conduct reconnaissance flights over each other's territories to collect information about military forces and activities. More than 1,500 flights have been conducted under the treaty, aimed at fostering transparency about military activity and helping monitor arms control and other agreements.
President Donald Trump pulled out of the Open Skies Treaty, arguing that Russian violations made it untenable for the United States to remain a party. The U.S. completed its withdrawal from the pact in November.
Russia denied breaching the treaty, which came into force in 2002. The European Union has urged the U.S. to reconsider and called on Russia to stay in the pact and lift flight restrictions, notably over its westernmost Kaliningrad region, which lies between NATO allies Lithuania and Poland.
Russia has argued that the limits on flights over Kaliningrad, which hosts sizable military forces, are permissible under the treaty's terms, noting that the U.S. has imposed more sweeping restrictions on observation flights over Alaska.
As a condition for staying in the pact after the U.S. pullout, Moscow unsuccessfully sought guarantees from NATO allies that they wouldn't transfer the data collected during their observation flights over Russia to the U.S.
Leonid Slutsky, head of the foreign affairs committee in the lower house of the Russian parliament, said in televised remarks Friday that Russia could review its decision to withdraw if the U.S. decides to return to the pact, but acknowledged that the prospect looks "utopian."
Moscow has warned that the U.S. withdrawal will erode global security by making it more difficult for governments to interpret the intentions of other nations, particularly amid Russia-West tensions after the Russian annexation of Ukraine's Crimea in 2014.
The demise of the Open Skies Treaty comes after the U.S. and Russian withdrawal in 2019 from the Intermediate-Range Nuclear Forces Treaty.
The nuclear treaty, which was signed in 1987 by President Ronald Reagan and Soviet leader Mikhail Gorbachev, banned land-based cruise and ballistic missiles with a range of 310 to 3,410 miles, weapons seen as particularly destabilizing because of the shorter time they take to reach targets compared with intercontinental ballistic missiles.
The only U.S.-Russian arms control pact still standing is the New START treaty that expires in three weeks. Moscow and Washington have discussed the possibility of its extension, but have so far failed to overcome their differences.
Biden has spoken for the preservation of the New START treaty and Russia has said it's open for its quick and unconditional extension. But negotiating the deal before the pact expires Feb. 5 appears extremely challenging.
