US Secretary of State Antony Blinken and Russian Foreign Minister Sergey Lavrov met on the sidelines of the G20 summit in New Delhi on Thursday. Blinken said he urged Russia to return to the New START arms control treaty, but Moscow has already insisted that Washington's "hybrid war" on Russia makes serious discussions impossible.

The two diplomats met for around ten minutes. Russian Foreign Ministry Spokeswoman Maria Zakharova told reporters that Blinken "asked for contact" with Lavrov. However, the brief encounter was conducted on the fly and could not be considered "negotiations," she added.

In his own press conference after the meeting, Blinken said that he reaffirmed the US' support for Ukraine, raised the possibility of a prisoner exchange for jailed American Paul Whelan, and "urged Russia to reverse its irresponsible decision and return to implementing the New START treaty."

Russian President Vladimir Putin signed a law this week to suspend the treaty, which was the last remaining nuclear arms agreement between the US and Russia. The treaty placed limits on the number of deployed missiles, bombers, launchers, and warheads each side could possess, and allowed both countries to inspect each others' nuclear sites.

Earlier this week, Russia's ambassador to the US, Anatoly Antonov, said that "Washington must reconsider its hostile anti-Russian policy" before Moscow would contemplate a return to the agreement. Given that the US has "launched and dragged its European allies into a large-scale hybrid war against Russia," and insists on inspecting the same Russian bases that its Ukrainian proxies are attacking "with the help of the Pentagon," the deal would remain suspended.

Antonov also accused the US of violating the treaty long before Russia's withdrawal, while Kremlin spokesman Dmitry Peskov said a day later that Washington's actions prior to the outbreak of conflict in Ukraine – which included rejecting all of Russia's security requests – showed that "they were not ready to talk about anything with us."
