Lavrov also said the question of when Russia will negotiate an end to the war should be put to Ukraine President Volodymyr Zelensky. Earlier in the day Blinken had met with his counterparts from the Quad, as the grouping is informally called, and they issued a statement saying "the use or threat of use of nuclear weapons is inadmissible". Late last month, Russian President Vladimir Putin suspended a landmark nuclear arms control treaty and threatened to resume nuclear tests. During their brief exchange on the sidelines of the G20 meeting on Thursday, Blinken told Lavrov to end the war and urged Moscow to reverse its suspension of the New START (Strategic Arms Reduction Treaty) on nuclear weapons. China has denounced the Quad as a Cold War construct and a clique "targeting other countries".
