Trump Says He Will Call Putin to Discuss Ending Ukraine War

President Trump said he would speak with President Vladimir V. Putin of Russia on Tuesday, as he continued to express optimism that Russia would agree to a proposal to halt fighting in Ukraine for 30 days.

“We want to see if we can bring that war to an end,” Mr. Trump told reporters aboard Air Force One on Sunday evening. “Maybe we can. Maybe we can’t, but I think we have a very good chance.”

Mr. Trump said that progress on negotiations had been made over the weekend, and there have been ongoing discussions about “dividing up certain assets,” specifically mentioning concessions over land and power plants.

“I think we’ll be talking about land, it’s a lot of land. It’s a lot different than it was before the war, as you know,” Mr. Trump said.

He added: “We’ll be talking about power plants. That’s a big question. But I think we have a lot of it already discussed very much by both sides — Ukraine and Russia.”

Steve Witkoff, the U.S. special envoy to the Middle East who has been involved in the peace talks, said Sunday on CNN that he had a positive meeting with Mr. Putin last week that lasted three to four hours. He declined to share the specifics of their conversation, but he said the two sides had “narrowed the differences between them.”

Ukraine has already agreed to support the U.S.-backed cease-fire, and President Volodymyr Zelensky of Ukraine has accused Mr. Putin of purposely delaying negotiations while trying to trap Ukrainian forces to improve his position in the cease-fire talks.
