President Donald Trump said he's "very angry" about Russia's strikes on Ukraine after his recent summit with Russian President Vladimir Putin to broker a peace deal.

"Every conversation I have with him is a good conversation," Trump told reporters during an executive order signing event at the Oval Office via ABC News. "And then unfortunately, a bomb is loaded up into Kyiv or someplace, and then I get very angry about it."

Trump admonished Putin for the Kremlin's nightly attacks on Ukrainian cities, but still expressed optimism that a peace deal between the two countries would be reached.

"I think we're going to get the war done," Trump said via ABC News, but added, "You never know what's going to happen in a war. Strange things happen in war. The fact that [Putin] went to Alaska, our country, I think, was a big statement that he wants to get it done."

Putin, who met with Trump on August 15 for a summit in Anchorage, Alaska, is reportedly demanding that Ukraine surrender the eastern Donbas region, renounce desires to join NATO and remain neutral and keep Western troops out of the war-torn country, three sources familiar with his thinking confirmed to Reuters on August 22. The Russian sources said Putin had laid out territorial demands in June 2024, which require Ukraine to cede the four provinces -- Donetsk, Luhansk, Kherson and Zaporizhzhia -- since occupied by Russia during the three-and-a-half-year war.

German Chancellor Friedrich Merz told reporters that Putin and Ukrainian President Volodymyr Zelenskyy could potentially meet in-person within the next two weeks. Merz, who was among the European leaders that joined Zelenskyy at the White House on August 18, said that Putin agreed to a potential meeting at a yet to be determined location during a phone call with Trump.

Trump reportedly called Putin, who “agreed that there would be a meeting between the Russian president and the Ukrainian president within the next two weeks,” during a pause in discussions with the European leaders, according to Merz. Trump reportedly proposed that a meeting between the two leaders was necessary for peace negotiations to "truly begin" three-and-a-half years after Russia invaded Ukraine, Merz added.

“We don’t know whether the Russian president will have the courage to attend such a summit. Therefore, persuasion is needed,” he said.

Trump said he was "very happy" with the progress made during Monday's discussion with Zelenskyy and the other European leaders, which took place three days after his summit with Putin in Alaska.

"Everyone is very happy about the possibility of PEACE for Russia/Ukraine," Trump wrote on his Truth Social account. "At the conclusion of the meetings, I called President Putin, and began the arrangements for a meeting, at a location to be determined, between President Putin and President Zelenskyy. After that meeting takes place, we will have a Trilat, which would be the two Presidents, plus myself. Again, this was a very good, early step for a War that has been going on for almost four years. Vice President JD Vance, Secretary of State Marco Rubio, and Special Envoy Steve Witkoff, are coordinating with Russia and Ukraine. Thank you for your attention to this matter!
