Ukraine’s top negotiator is scheduled on Thursday to meet in Florida with U.S. special envoy Steve Witkoff, two days after the American’s high-stakes meeting with Russian President Vladimir Putin in Moscow, according to a senior administration official.

President Donald Trump’s son-in-law Jared Kushner is also expected to be in the meeting with Rustem Umerov, the secretary of Ukrainian National Security and Defense Council, the official said.

Ukrainian President Volodymyr Zelenskyy confirmed on Wednesday that preparations were underway for further discussions, but did not disclose when the talks were expected.

“We’re preparing meetings in the United States — after the American team returns from Moscow and following the relevant consultations in Washington — Rustem Umerov, Andrii Hnatov, along with the rest of the negotiating team, will continue discussions with envoys of President Trump,” Zelenskyy said on social media.

Few details were released about what had been discussed during the five-hour meeting between Witfkoff, Kushner and Putin, but post-talks comments made by Washington and Moscow were mostly positive. Both parties acknowledged that more work would have to be done to make the deal acceptable to both Kyiv and Moscow.

Kremlin spokesperson Dmitry Peskov said Putin had found some terms “unacceptable,” but added that others were fine for Moscow. And Trump described it as a “reasonably good meeting.”

Trump said Witkoff and Kushner relayed their “impression” that Putin “would like to see the war ended.”
