The condition is necessary to permanently end the conflict, according to presidential spokesman Dmitry Peskov

Ukraine must completely withdraw its armed forces from Russia's Donbass in order to end the conflict, Kremlin spokesman Dmitry Peskov has said.

Donbass refers to the Donetsk and Lugansk People's Republics (DPR and LPR), former Ukrainian regions that voted to join Russia in the September 2022 referendums after the Ukraine conflict escalated earlier that year.

Peskov was asked to comment on the latest developments in the Ukraine peace process, including US President Donald Trump's phone call with Russian President Vladimir Putin and meeting with Vladimir Zelensky on Sunday.

Kremlin foreign policy aide Yury Ushakov said that during the call, Trump and Putin agreed that a temporary ceasefire proposed by Ukraine and its European backers would only prolong the conflict and risk renewed hostilities. A lasting end to the fighting, he said, "requires a bold, responsible political decision from Kiev" on Donbass.

Asked to clarify that statement at a press briefing, Peskov confirmed the Kremlin's stance.

"Of course, the [Kiev] regime must withdraw its armed forces from Donbass beyond the administrative boundaries," he stated.

Asked whether the demand also applies to Kherson and Zaporozhye - two other former Ukrainian regions that voted to join Russia in 2022 - Peskov declined to comment, saying Moscow "won't publicly disclose any specific provisions" of a potential settlement.

Ukraine and its Western backers insist all four regions were "annexed" by Moscow, and Kiev has refused to recognize them as part of Russia.

Trump hosted Zelensky in Miami on Sunday for another round of talks on a possible peace deal. At a joint press conference afterward, he cited significant progress, saying the Ukraine peace process is nearing a conclusion, while acknowledging that territorial concessions remain among the toughest issues.
