NEW DELHI, March 2 - U.S. Secretary of State Antony Blinken and Russian Foreign Minister Sergey Lavrov talked briefly Thursday in the highest-level in-person talks between the two countries since Russia’s invasion of Ukraine. But there was no indication of any movement toward easing the intense tensions between their two nations.

The short encounter came as relations between Washington and Moscow have plummeted over Russia’s war with Ukraine and tensions have soared amid a myriad of disagreements, complaints and recriminations on other matters ranging from arms control to embassy staffing and prisoners.

U.S. officials said Blinken and Lavrov chatted for roughly 10 minutes on the sidelines of the G-20 conference of foreign ministers in New Delhi, The Associated Press reported. But there was no sign of any progress and the conference itself ended with the grouping unable to reach consensus on the Ukraine war.

Still, with relations at perhaps their lowest point since the Cuban Missile Crisis during the Cold War, the mere fact that the two men met showed that, at least for the moment, lines of high-level communication between Washington and Moscow remains open.

At a news conference, Blinken said he told Lavrov that the U.S. would continue to support Ukraine for as long as it takes and would push for the war to end through diplomatic terms that Kyiv agrees to.

“End this war of aggression, engage in meaningful diplomacy that can produce a just and durable peace,” Blinken said he had told Lavrov. But, he noted that “President Putin has demonstrated zero interest in engaging, saying there’s nothing to even talk about unless and until Ukraine accepts and I quote ‘the new territorial reality’.””

Earlier, Blinken had told the G-20 meeting that Russia’s war with Ukraine could not go unchallenged.

“We must continue to call on Russia to end its war of aggression and withdraw from Ukraine for the sake of international peace and economic stability,” Blinken said. He noted that 141 countries had voted to condemn Russia at the United Nations on the one-year anniversary of the invasion.

Yet, several members of the G-20, including host India, China and South Africa, chose to abstain in that vote and despite appeals from top Indian officials to look beyond their differences over Ukraine and forge consensus on other issues, the foreign ministers were unable to do so or agree on a final communique.

China and Russia objected to two paragraphs taken from the previous G-20 declaration in Bali last year, according to a summary of Thursday’s meeting released by India. And Blinken lamented that “Russia and China were the only two countries that made clear that they would not sign off on the text.”

The paragraphs stated that the war in Ukraine was causing immense human suffering while exacerbating fragilities in the global economy, the need to uphold international law, and that “the use or threat of use of nuclear weapons is inadmissible.” (ap/ez)
