The Kremlin said on Monday that Ukraine should withdraw its troops from the parts of Donbas it still controls if it wants peace, warning that Kyiv could lose additional territory if it fails to reach a deal with Moscow.

Kremlin spokesman Dmitry Peskov said Russian President Vladimir Putin and U.S. President Donald Trump, who spoke on Sunday ahead of Trump’s meeting in Miami with Ukrainian President Volodymyr Zelenskiy, were expected to hold another call soon.

Russia currently controls around one-fifth of Ukraine, including Crimea, which it annexed in 2014, about 90% of Donbas, roughly three-quarters of the Zaporizhzhia and Kherson regions, and small parts of the Kharkiv, Sumy, Mykolaiv and Dnipropetrovsk regions, according to Russian estimates.

Russia claims Donbas, Zaporizhzhia and Kherson as its own territory, though most countries recognise them as part of Ukraine.
