President Donald Trump said Thursday that he would meet with Russian President Vladimir Putin even if the Russian leader won’t meet with Ukrainian President Volodymyr Zelensky. Trump, when asked by a reporter if Putin would need to meet with Zelenskyy in order to secure a meeting with the U.S., said: “No, he doesn’t. No.” His comments followed Putin 's remarks earlier in the day that he hoped to meet with Trump next week, possibly in the United Arab Emirates. But the White House was still working through the details of any potential meetings, press secretary Karoline Leavitt said. Putin’s announcement came on the eve of a White House deadline for Moscow to show progress toward ending the 3-year-old war in Ukraine or suffer additional economic sanctions. When asked Thursday at the White House whether his deadline for Friday would hold, Trump said of Putin: "It’s going to be up to him. We’re going to see what he has to say. It’s going to be up to him. Very disappointed.” The president also touched on killings that have continued on both sides and added, “I don’t like long waits. I think it’s a shame.” A White House official told The Associated Press on Thursday morning that a U.S.-Russian summit would not happen if Putin did not agree to meet with Zelenskyy, but the official later said it only made it less likely. The official was not authorized to speak publicly and had spoken on condition of anonymity. Speaking of possible direct talks with Zelenskyy, Putin said he has mentioned several times that he was not against it, adding: “It’s a possibility, but certain conditions need to be created” for it to happen. The Kremlin has previously said that Putin and Zelenskyy should meet only when an agreement negotiated by their delegations is close. Ukraine fears being sidelined by direct negotiations between Washington and Moscow, and Zelenskyy said he had phone conversations with several European leaders Thursday amid a flurry of diplomatic activity. European countries have pledged to back Ukraine for as long as it takes to defeat Russia's invasion. Putin’s foreign affairs adviser, Yuri Ushakov, earlier brushed aside the possibility of Zelenskyy joining the summit, something the White House said Trump was ready to consider. Putin has spurned Zelenskyy’s previous offers of a meeting to clinch a breakthrough. “We propose, first of all, to focus on preparing a bilateral meeting with Trump, and we consider it most important that this meeting be successful and productive,” Ushakov said, adding that U.S. special envoy Steve Witkoff's suggestion of a meeting including Ukraine's leader “was not specifically discussed.” Putin made the announcement in the Kremlin about a possible meeting with Trump after meeting with Sheikh Mohammed bin Zayed Al Nahyan, the president of the UAE. Asked who initiated the possible talks with the American president, Putin said that didn't matter and “both sides expressed an interest.” Kirill Dmitriev, the head of Russia's sovereign wealth fund who met with Witkoff on Wednesday, said a Trump-Putin meeting would allow Moscow to “clearly convey its position," and he hoped a summit would include discussions on mutually beneficial economic issues, including joint investments in areas such as rare earth elements.
