State Department spokeswoman Tammy Bruce has said it's time for the two nations to come up with their own proposals to resolve the conflict

The US will no longer serve as mediator in negotiations between Russia and Ukraine, State Department spokeswoman Tammy Bruce has said. Speaking at a regular press briefing on Thursday, she stated it was time for the two parties to propose their own solutions and engage in direct talks.

Trump had previously pledged to end the Ukraine conflict "within 24 hours" if elected, though he later described the claim as an "exaggeration." Since taking office in January, he has pressed both sides for a ceasefire but has expressed frustration over the slow progress in the talks. Trump has warned that the US may withdraw from the peace process if it continues to falter.

Earlier, Moscow signaled it's ready to start direct negotiations with Kiev "without preconditions," while Russian President Vladimir Putin ordered Russian forces to observe a short ceasefire during Victory Day celebrations next week. Ukrainian leader Vladimir Zelensky has branded the Russian truce announcement a "manipulation."

"We will not be the mediators," Bruce told reporters when asked about Washington's future role. "We certainly are still committed to it and we'll help and do what we can, but we are not going to fly around the world at the drop of a hat to mediate meetings."

"It's time for both of the nations involved in this conflict to come up with concrete proposals about how this conflict ends. It's going to be up to them," Bruce added.

Her remarks contrasted with comments by US Vice President J.D. Vance, who said earlier this week that Washington planned to dedicate another 100 days to mediating a peace deal.

Media reports have claimed the US peace proposal includes recognizing Russia's sovereignty over Crimea and its de-facto control over parts of four former Ukrainian regions that chose to join Russia. It also reportedly calls for "freezing" the conflict along current front lines.

Commenting on Moscow's decision to halt military operations next week, Russian Foreign Minister Sergey Lavrov said the pause should serve as "the start of direct negotiations with Kiev without preconditions." Kiev, however, demanded an immediate, unconditional 30-day ceasefire.
