Ukrainian President Volodymyr Zelenskiy said negotiators remain split over territorial concessions in a US-brokered peace plan, Bloomberg News reported on Monday, citing a phone interview with Zelenskiy.

Elements of the US proposal require further discussion on “sensitive issues,” including security guarantees for Ukraine and control of its eastern territories, according to the report.

“There are visions of the US, Russia and Ukraine – and we don’t have a unified view on Donbas,” Zelenskiy told Bloomberg News early Monday.

He added that Kyiv is seeking a separate pact on security guarantees from Western allies, particularly the US, the report said.

Zelenskiy is scheduled to meet British, French and German leaders in London on Monday to rally support, as Washington steps up pressure on Kyiv to accept the proposed peace deal with Russia.

US officials said they are close to finalising the agreement, though neither Ukraine nor Russia has shown willingness to sign the deal drafted by Trump’s team.
