The US president has previously accused Vladimir Zelensky of undermining his peace efforts

US President Donald Trump has said he expected Vladimir Zelensky to be much "easier to deal with" than Russian President Vladimir Putin, but indicated he still hopes Kiev will accept Washington's proposal to end the conflict in Ukraine.

Zelensky has publicly rejected one of the key points in the proposed US peace framework, insisting earlier this week that Kiev will neven even discuss formally recognizing Crimea as Russian territory. The White House criticized him for revealing sensitive details of the negotiations - while President Trump warned that he risks losing the entire country if he continues to stall talks with Moscow.

"I think Russia is ready... I think we have a deal with Russia. We have to get a deal with Zelensky," Trump told journalists at the White House on Wednesday.

The US president added, "that's okay, it's alright," expressing hope that "we'll have a deal with both."

Earlier on Wednesday, Trump warned in a post on Truth Social that Zelensky holds a weak bargaining position. "The situation for Ukraine is dire - He can have Peace or, he can fight for another three years before losing the whole Country," he wrote.

Trump declined to say whether he intends to meet Zelensky when both are expected to attend the funeral of Pope Francis later this week. "I don't know if he is going to the funeral or not... I just hope he gets this thing solved," Trump told reporters.

Asked whether he expects to meet Putin during a planned visit to Saudi Arabia next month, Trump said it was "possible, but most likely not... I think we'll meet with him shortly thereafter."

The US has been pushing for a resolution to the conflict, while also seeking to secure a minerals extraction agreement with Ukraine to help offset the billions of dollars it has spent supplying weapons and aid.

However, Trump and his administration have grown increasingly frustrated with the slow pace of negotiations on both fronts. Secretary of State Marco Rubio warned on Tuesday that if progress stalls, the US may walk away from the talks. "If not enough movement is happening, we may need to move on to other priorities," he said.

White House press secretary Karoline Leavitt also voiced Trump's frustration with Zelensky. "Unfortunately, Zelensky has been trying to litigate this peace negotiation in the press, and that's unacceptable to the president," Leavitt said on Wednesday.

Kremlin spokesman Dmitry Peskov noted that a peace deal with Ukraine is unlikely to be concluded in an expedited manner due to the complexities of the negotiations. Moscow has said it has always been ready to engage in peace talks, provided they ensure a permanent solution that addresses the root causes of the conflict - while any temporary ceasefire would be used by Ukraine's Western backers to rearm the country's military.
