President Trump intends to meet in person with President Vladimir V. Putin of Russia as soon as next week, and he plans to follow up shortly afterward with a meeting between himself, Mr. Putin and President Volodymyr Zelensky of Ukraine, according to two people familiar with the plan.

Mr. Trump disclosed his plans in a call with European leaders on Wednesday, the people said. The meetings would include only those three men, and would not include any European counterparts. The European leaders, who have tried to play a coordinating role on meetings to end the violence between Russia and Ukraine while supporting their European neighbor, appeared to accept what Mr. Trump said, one of the people familiar with the call said.

It was not immediately clear if Mr. Putin or Mr. Zelensky had agreed to the plan Mr. Trump described. But Mr. Zelensky was on Mr. Trump’s call with European leaders, saying in a statement afterward that he had a “conversation with President Trump” and that his and European leaders’ position was that “the war must end,” but “an honest end.”

The call also included the leader of the United Kingdom, the German chancellor and the NATO secretary general, along with Vice President JD Vance, Secretary of State Marco Rubio and Mr. Trump’s special envoy, Steve Witkoff.

Mr. Trump gave some details of the call in a post on his social media site, saying Mr. Witkoff had met for several hours in Russia with Mr. Putin. He did not mention his plans for his own summits.

“Afterwards, I updated some of our European Allies,” Mr. Trump wrote on his social media site, Truth Social. “Everyone agrees this War must come to a close, and we will work towards that in the days and weeks to come. Thank you for your attention to this matter!”

Mr. Trump held a one-on-one meeting with Mr. Zelensky at the funeral of Pope Francis in Rome earlier this year. The president of France, Emmanuel Macron, tried joining the meeting — which took place in St. Peter’s Basilica — but was rebuffed by Mr. Trump, who generally prefers bilateral meetings.

A White House spokesman did not immediately respond to a request for comment. Spokesmen for Mr. Witkoff and Mr. Vance, and a spokeswoman for Mr. Rubio, did not immediately respond to a request for comment.

Mr. Putin’s spokesman, Dmitri S. Peskov, also did not immediately respond to a request for comment.

Mr. Trump has been stymied for months in his efforts to find a peace agreement between Russia and Ukraine, after more than three years of war. Mr. Trump has been a skeptic of U.S. military aid to Ukraine, and he dressed down Mr. Zelensky in a remarkable Oval Office meeting as cameras rolled earlier this year. Still, in frustration with the slow pace of talks with Russia, Mr. Trump recently authorized more arms sales to NATO allies that are intended for Ukraine.

Mr. Trump has tried giving Mr. Putin room to come to the negotiating table over several months. But more recently, he has publicly excoriated Mr. Putin, suggesting the Russian leader was simply playing him for time after repeated conversations with Mr. Witkoff.

Mr. Witkoff’s latest visit to Moscow came as Mr. Trump has threatened secondary sanctions against Russia amid the lack of progress toward peace.
