The top diplomats of the United States and Russia spoke Friday for the first time since the Ukraine war, with Secretary of State Antony Blinken describing a "frank" exchange as he pushed to free two Americans.

Blinken initiated the call with Foreign Minister Sergei Lavrov, whom he had shunned as early as a few weeks ago, as he pressed Russia to accept an offer to free prisoners.

"We had a frank and direct conversation. I pressed the Kremlin to accept the substantial proposal that we put forth on the release of Paul Whelan and Brittney Griner," Blinken told reporters.

President Joe Biden has faced growing public pressure to find a way home for Griner, a basketball star jailed for transport of cannabis oil, and Whelan, a former Marine jailed on espionage charges he denies.

Blinken declined to characterize Lavrov's reaction, saying, "I can't give you an assessment of whether I think things are any more or less likely."

"But it was important that he heard directly from me on that," Blinken said.

Russia's foreign ministry, in a statement on the call, said that relations between the two nations "are in strong need of normalization."

"As for a potential swap of Russian and American prisoners, the Russian side insisted that we return to a regime of professional dialogue, free of media speculation, in the framework of discreet diplomacy," it said.

Lavrov also denounced the US military and NATO for their supply of billions of dollars of weapons to Ukraine, saying it "only prolonged the agony of the Kyiv regime, extending the conflict and its victims." the foreign ministry said.

The US proposal, sent quietly to Russia several weeks earlier, reportedly includes swapping the two Americans for convicted Russian arms smuggler Viktor Bout and would follow a similar prisoner exchange in April.

Blinken said he also pressed Lavrov on Russia honoring a Turkish-brokered proposal to ship grain out of Ukraine and on purported plans by Moscow to annex additional parts of Ukraine seized by Russian troops.

Blinken said he told Lavrov that the world will not recognize annexation.

"It was very important that the Russians hear directly from us that that will not be accepted -- and not only will it not be accepted, it will result in additional significant costs being imposed upon Russia if it follows through," Blinken said.

Blinken said Russia was preparing "sham referendums" to try to "falsely demonstrate that the people in these parts of Ukraine somehow seek to become part of Russia."

The votes would be part of Russian President Vladimir Putin's objective of "gobbling up as much Ukrainian territory as he can," he added.

The telephone conversation was the first between Blinken and Lavrov since February 15, when the top US diplomat warned Russia against invading Ukraine, repeating a message he delivered in person in Geneva a month earlier.

Putin went ahead and attacked nine days later, leading the United States and its allies to impose sweeping sanctions and to seek to isolate Russia on the world stage.

Blinken refused to meet Lavrov when they both attended talks in early July in Bali of the Group of 20 major economies.

State Department spokesman Ned Price said Blinken had no plans to meet Lavrov next week when they are both in Cambodia for a Southeast Asian meeting.
