The White House said President Donald Trump will only sit down with Russian President Vladimir Putin if the Kremlin leader also agrees to meet Ukrainian President Volodymyr Zelensky. A U.S. official, confirming multiple media reports, added that no venue or date has been determined for any talks. The condition follows a Kremlin announcement earlier on Thursday that Moscow and Washington had agreed "in principle" to hold a one-on-one summit as soon as next week. Washington has not endorsed that claim, and Putin told reporters he was open to seeing Zelensky "under the right conditions," while pointing out the two leaders have not spoken directly since Russia’s full-scale invasion in 2022. Expectations of renewed diplomacy lifted Russian equities, which climbed roughly 4.5% after the Kremlin’s statement. U.S. officials said they will not proceed with planning unless Moscow accepts the three-way format aimed at advancing negotiations to end the war in Ukraine.
