The United States remains committed to supporting peace efforts in Ukraine but will scale back its direct role as mediator, State Department spokesperson Tammy Bruce said on May 1.
"He (U.S. President Donald Trump) knows also that there is another part of the world, a whole globe that needs some attention," Bruce told reporters.
"We are not going to fly around the world at the drop of a hat to mediate meetings; that is now between the two parties, and now is the time that they need to present and develop concrete ideas about how this conflict is going to end."
The remarks reflect a significant shift in Washington's approach after months of stalled diplomacy aimed at brokering a ceasefire in Russia's full-scale war against Ukraine.
Secretary of State Marco Rubio and Trump had previously warned that the U.S. would withdraw from mediation efforts if no meaningful progress was made.
