Much remains unclear at this stage following the nearly three-hour meeting.

Putin said he and his counterpart had reached an "agreement," though did not provide any further details on what was agreed to.

Trump did not mention any agreement. He said there was "great progress" on several points but did not provide any further details. He also did not go into detail on what areas they still need to iron out.

He stopped short of announcing a ceasefire, which was a priority of Trump's for Friday's summit.

Trump said he will call up NATO and, "of course," Ukrainian President Volodymyr Zelenskyy to discuss Friday's meeting.

"So ultimately, up to them," he said.

Neither Putin nor Trump took any questions from the hundreds of reporters gathered in the room, instead quickly shaking hands before leaving the stage.

In brief remarks following Putin's lengthier address to reporters, Trump called the negotiations "extremely productive" and that "many points" were agreed to but, "There's no deal until there's a deal."

He said there are a few more points to get to, including one that was "most significant," but didn't go into detail as to what that was.

"We didn't get there, but we have a very good chance of getting there," he said.

He made no mention of a ceasefire.

Speaking in Russian through a State Department interpreter, Russian President Vladimir Putin spoke first at the joint press briefing.

He began talking about how Russia and the U.S. are "close neighbors" and that this can mark a new stage of rebuilding and fostering "mutually beneficial and equal ties."

Putin said he has "every reason to believe that moving down this path, we can come to the end of the conflict in Ukraine."
