Putin signs extension of last Russia-U.S. nuclear arms treaty

Russian President Vladimir Putin on Friday signed a bill extending the last remaining nuclear arms control treaty between Russia and the United States a week before the pact was due to expire.

Both houses of the Russian parliament voted unanimously Wednesday to extend the New START treaty for five years. Putin and U.S. President Joe Biden had discussed the nuclear accord a day earlier, and the Kremlin said they agreed to complete the extension procedures in the next few days.

New START expires Feb. 5. The pact’s extension doesn’t require congressional approval in the U.S., but Russian lawmakers had to ratify the move. Russian diplomats said the extension will be validated by exchanging diplomatic notes once all the procedures are completed.

The treaty, signed in 2010 by President Barack Obama and Russian President Dmitry Medvedev, limits each country to no more than 1,550 deployed nuclear warheads and 700 deployed missiles and bombers, and envisages on-site inspections to verify compliance.

Biden indicated during the U.S. presidential campaign that he favoured the preservation of New START.

Russia had long proposed prolonging the pact without any conditions or changes, but the administration of former president Donald Trump waited until last year to start talks and made the extension contingent on a set of demands. The talks stalled, and months of bargaining failed to narrow differences.

After both Moscow and Washington withdrew from the 1987 Intermediate-range Nuclear Forces Treaty in 2019, New START is the only remaining nuclear arms control deal between the two countries.

Earlier this month, Russia announced that it would follow the U.S. in pulling out of the Open Skies Treaty, which allowed surveillance flights over military facilities to help build trust and transparency between Russia and the West.

Arms control advocates hailed New START’s extension as a boost to global security and urged Russia and the U.S. to negotiate followup agreements.

Russian Deputy Foreign Minister Sergei Ryabkov, the country’s lead negotiator on New START, said earlier this week that Russia was ready to sit down for talks on prospective arms cuts that he indicated should also involve non-nuclear precision weapons with strategic range.
