U.S. President Donald Trump said he and Russian President Vladimir Putin had "very productive" talks in Alaska Friday but left without reaching a deal to end the war in Ukraine.

For his part, Putin said he and Trump reached an “understanding” and suggested a meeting in Moscow could be next.

The much-anticipated summit between U.S. President Donald Trump and Russian leader Vladimir Putin began with a warm welcome and a flyover by screaming jets at a U.S. military base in Alaska but ended with a thud after they conceded that they had failed to reach any agreements on how to end the Russia-Ukraine war.

After about 2 1/2 hours of talks at Joint Base Elmendorf-Richardson in Anchorage, the two men appeared before reporters for what had been billed as a joint news conference — but they took no questions.

“We had an extremely productive meeting and many points were agreed to, there are just a very few that are left,” Trump said. “We didn’t get there, but we have a very good chance of getting there.”

Putin, who spoke first after the meeting concluded, lauded the historical relationship between the United States, Russia and the former Soviet Union, recalling joint missions conducted by the two countries during World War II.

He said the U.S. and Russia share values, a standard talking point for Russian officials when trying to woo Trump and his aides.

The U.S. president said “some great progress” had been made during “an extremely productive meeting." Trump said “many points were agreed to" and that “just a very few” issues were left to resolve. He did not offer specifics.

He also made no reference to the ceasefire he's been seeking and did not criticize Putin over the killing of Ukrainian civilians as he stood on the world stage.

As they wrapped up, Putin said he hoped the two would meet again soon.

“Next time in Moscow," he said in English, then chuckled.
