New Delhi: US Secretary of State Antony Blinken and Russian Foreign Minister Sergey Lavrov talked briefly Thursday at a meeting of top diplomats from the Group of 20 nations in the first high-level meeting in months between the two countries.

US officials said Blinken and Lavrov chatted for roughly 10 minutes on the sidelines of the G-20 conference in New Delhi. The short encounter came as relations between Washington and Moscow have plummeted while tensions over Russia’s war with Ukraine have soared.

A senior US official said Blinken used the discussion to make three points to Lavrov: that the US would support Ukraine in the conflict for as long as it takes to bring the war to an end, that Russia should reverse its decision to suspend participation in the New START nuclear treaty and that Moscow should release detained American Paul Whelan.

The official, who spoke to reporters on condition of anonymity, declined to characterise Lavrov’s response but said Blinken did not get the impression that there would be any change in Russia’s behaviour in the near term.

Russia had no immediate comment on the substance of the conversation, but Russian Foreign Ministry spokesperson Maria Zakharova said Blinken had asked to speak to Lavrov.

It was their first contact since last summer, when Blinken called Lavrov by phone about a US proposal for Russia to release Whelan and formerly detained WNBA star Brittney Griner. Griner was later released in a swap for imprisoned Russian arms dealer Viktor Bout but Whelan remains detained in Russia after being accused of spying.

The last time Blinken and Lavrov met in person was in Geneva, Switzerland, in January 2022 on the eve of Russia’s attack. At that meeting, Blinken warned Lavrov about consequences Russia would face if it went ahead with its planned military operation but also sought to address some complaints that Russian President Vladimir Putin had made about the US and Nato

Those talks proved to be inconclusive as Russia moved ahead with its plans to attack and Blinken then cancelled a scheduled follow-up meeting with Lavrov that was set for just two days before Moscow eventually attacked on Feb. 24, 2022.

The two men have attended several international conferences together since the war began, notably the last G-20 foreign ministers’ meeting in Bali, Indonesia, last year, but had not come face-to-face until Thursday.
