NEW DELHI (AP) U.S. 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.

U.S. 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 Russias war with Ukraine have soared.

A senior U.S. official said Blinken used the discussion to make three points to Lavrov: that the U.S. 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 to discuss the private conversation, said Blinken had disabused Lavrov of any idea they might have that U.S. support for Ukraine is wavering.

The official declined to characterize Lavrovs response but said Blinken did not get the impression that there would be any change in Russias behavior 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.
