U.S. President Donald Trump said he will meet with Russian President Vladimir Putin on Aug. 15 in Alaska. 

Trump announced the meeting in a post on social media and said more details would follow.

The announcement came after Trump said Friday that he would meet "very shortly" with Putin to discuss ending the war in Ukraine, a potential major milestone after expressing weeks of frustration that more was not being done to quell the fighting.

Speaking to reporters at the White House earlier in the day, he also suggested that his meeting with the Russian leader could come before any sit-down discussion involving Ukrainian President Volodymyr Zelenskyy.

"We're going to have a meeting with Russia, start off with Russia," Trump said.

If it happens, the meeting would be the first U.S.-Russia summit since 2021, when former President Joe Biden met Putin in Geneva. It could mean a breakthrough in Trump's effort to end the war, although there's no guarantee it would stop the fighting since Moscow and Kyiv remain far apart on their conditions for peace.    

There was no immediate confirmation from Moscow.

Trump also said that a peace deal would likely mean "there will be some swapping of territories" between Ukraine and Russia but didn't provide further details.

Analysts, including some close to the Kremlin, have suggested that Russia could offer to give up territory it controls outside of the four regions it claims to have annexed.

Trump almost two weeks ago moved up his ultimatum to impose additional sanctions on Russia and introduce secondary tariffs targeting countries that buy Russian oil if the Kremlin did not move toward a settlement. The deadline was Friday.
