ISTANBUL

US President Donald Trump said Sunday that he is "a little bit disappointed" that Ukrainian President Volodymyr Zelenskyy has not yet read the latest peace proposal for ending the Russia-Ukraine war.

"We've been speaking to (Russian) President (Vladimir) Putin and we've been speaking to Ukrainian leaders, including Zelenskyy," Trump told reporters as he arrived at the Kennedy Center.

Trump said Russia is "fine" with the proposal, but added: "I'm not sure that Zelenskyy is fine with it. His people love it, but he hasn't read it.”

His remarks came hours after Zelenskyy said he had “substantive” talks with American officials after their consultations with a Ukrainian delegation in the US state of Florida.

The Ukrainian president said he had a phone call with US envoy Steve Witkoff and Trump’s son-in-law and informal adviser Jared Kushner along with senior Ukrainian negotiator Rustem Umerov and Chief of the General Staff Andrii Hnatov following talks to discuss Washington’s proposed peace plan to end the war.

Zelenskyy said they discussed “many aspects” and “key points” that could ensure an end to the over three-and-a-half-year Ukraine war and he is now awaiting a “detailed in-person report” from Umerov and Hnatov.

On Tuesday, Witkoff and Kushner met with Putin in Moscow for negotiations on the proposed plan, which presidential aide Yuri Ushakov said were “constructive, very useful, and informative.”
