MOSCOW—Russian President Vladimir Putin said Moscow would suspend its participation in the last remaining major nuclear-arms-control treaty between the U.S. and Russia, and vowed to continue the military campaign in Ukraine as the diplomatic gap between Moscow and the West widened.
He also said that if the U.S. were to test new types of nuclear weapons, Russia would do the same.
Mr. Putin’s remarks on the New Start treaty came during a wide-ranging state-of-the-nation address to Russia’s federal legislature in Moscow on Tuesday ahead of the Feb. 24 anniversary of the beginning of the invasion. He again blamed the West for provoking what he calls the “special military operation” in Ukraine.
President Biden is scheduled to give a speech later Tuesday in Poland, a day after offering continuing U.S. support to Ukraine during a visit to Kyiv.
