“I don’t know that he [Putin] would be there if I’m not there,” Trump told reporters on Air Force One as he flew from Saudi Arabia to Qatar.
“I know he would like me to be there, and that’s a possibility. If we could end the war, I’d be thinking about that,” he said.
Trump noted that he was already scheduled to be in the United Arab Emirates on Thursday on the third and final leg of his Gulf tour.
But when asked about visiting Turkey, he added: “That doesn’t mean I wouldn’t do it to save a lot of lives.”
US Secretary of State Marco Rubio is already planning to travel to Istanbul on Friday.
“Marco is going and Marco has been very effective,” Trump said.
Russia said its delegation would be in Istanbul on Thursday, but has given no details on who it will send.
‘This is his war’
Asked by AFP in a briefing on Wednesday who would travel from Moscow, Kremlin spokesman Dmitry Peskov declined to answer.
“The Russian delegation will be waiting for the Ukrainian delegation in Istanbul on May 15,” he said.
Peskov added that he would provide an update “when we get the relevant instructions from the president”, but “no such instructions have been received yet”.
Zelenskyy has urged Putin to come himself, saying that skipping the talks would signal an unwillingness by Moscow to seek peace and should be met with massive Western sanctions and more military aid for Kyiv.
“This is his war,” Zelenskyy said Tuesday. “Therefore, the negotiations should be with him.”
Trump took office vowing to end the conflict immediately and had put heavy pressure on Zelenskyy, whom he berated during a televised White House meeting on February 28.
Since then, the Trump administration has voiced frustration with Russia, which has snubbed an offer backed by Ukraine for an initial 30-day ceasefire.
Rubio has repeatedly threatened to give up on Russia-Ukraine diplomacy without progress, saying the United States has other priorities.
Despite the prospect of talks, the two sides’ positions on how the fighting should end remain far apart and there have been few signs either is willing to make concessions.
‘Dictated peace’
Brazilian President Luiz Inacio Lula da Silva, who in the past criticised the level of Western support for Ukraine, said he would also seek to persuade Putin to negotiate.
But Russian state media said Lula’s plane had stopped in Moscow after visiting Beijing, with RIA Novosti saying the Brazilian leader did not meet with Putin.
Earlier, Lula had told reporters in Beijing: “I’ll try to talk to Putin.”
He added: “It costs me nothing to say, ‘hey, comrade Putin, go to Istanbul and negotiate, dammit’.”
Lula last week visited Moscow to attend Russia’s Red Square military parade marking the defeat of the Nazis.
European leaders have also ramped up their pressure on Putin to come to the negotiating table personally.
German Chancellor Friedrich Merz said on Wednesday that there must not be any settlement in Ukraine in the form of a “dictated peace” from Moscow.
Addressing Parliament, Merz warned of “militarily created facts against Ukraine’s will”, telling lawmakers it was “of paramount importance that the political West does not allow itself to be divided”.
As preparations for the talks carried on, fighting continued to rage. A Russian missile strike on Ukraine’s northeastern city of Sumy killed at least one person on Wednesday afternoon, Ukrainian officials said.
