Trump also spoke with with Ukrainian leader Volodymyr Zelenskyy and European leaders in hopes of making progress toward a ceasefire.

“The conditions for that will be negotiated between the two parties, as it should be, because they have insights into aspects of the negotiation that no one else knows about,” Trump mentioned in a social media post.

“He and I will meet, and I think we’ll solve it or maybe not,” Trump told reporters after boarding Air Force One.

“At least we’ll know. And if we don’t solve it, it’ll be very interesting.”

Zelenskyy had discussions with Vance and US Secretary of State Marco Rubio in Rome on Sunday, alongside meetings with European leaders, upscaling his diplomatic engagements prior to the planned Monday calls.

The Ukrainian president shared on the social media platform X that in his discussions with the American officials, the talks in Turkey were addressed and noted that “the Russians dispatched a low-level delegation that lacks decision-making authority.” He further emphasized that Ukraine is deeply involved in “authentic diplomacy” aimed at achieving a ceasefire.

“We have also touched upon the need for sanctions against Russia, bilateral trade, defense cooperation, battlefield situation and upcoming prisoners exchange,” Zelenskyy said.

“Pressure is needed against Russia until they are eager to stop the war.”

The German government said Chancellor Friedrich Merz and French, British and Italian leaders spoke with Trump late Sunday about the situation in Ukraine and his upcoming call with Putin. A brief statement gave no details of the conversation, but said the plan is for the exchange to be continued directly after the Trump-Putin call.
