NATO chief Jens Stoltenberg warned Friday that the chances of saving a landmark Cold War arms treaty were decreasing day by day, after talks with Russian officials failed to yield any breakthrough.
Russia and the United States have both suspended their participation in the Intermediate-Range Nuclear Forces (INF), accusing each other of violating the accord, which banned a whole class of nuclear-capable missiles.
Washington will definitively quit the deal on August 2 unless Russia destroys a controversial new missile system the US and NATO say breaches the accord, signed in 1987 between US president Ronald Reagan and Soviet leader Mikhail Gorbachev.
NATO held talks with senior Russian officials as part of efforts to save the deal, a week after alliance defence ministers agreed a package of counter-measures in case Moscow ignores the deadline.
"We didn't see any sign of Russia being willing to come back into compliance with the INF treaty," Stoltenberg told reporters after the meeting, adding that the "ongoing Russian violation" was the only reason the treaty was under threat.
He said there was still time to save it, pointing to the speed with which Soviet forces were able to get rid of their medium-range weapons after the INF was signed.
"Back in 1987 Russia was able to destroy intermediate range cruise missiles in a few weeks," he said. "It is possible to do it in a few weeks because that has happened before."
