At the summit in Alaska on Friday night, Vladimir Putin offered a deal to freeze the front lines in Ukraine – in exchange for Ukraine withdrawing from the Donetsk and Luhansk regions, the Financial Times reported, citing four sources familiar with the talks.

Trump reportedly conveyed Putin's demands to Ukrainian President Volodymyr Zelensky during a phone call on Saturday, according to the newspaper.

Russia currently controls approximately 70 percent of the Donetsk region. However, the western part of the region remains under Ukrainian control and is described as very important for Ukraine's military operations and defense lines along the eastern front.

Putin: Didn't give up on the most important demands

Putin reportedly made it clear during the meeting that he had not abandoned his "fundamental demands" to "resolve the root causes of the conflict" - demands that would mean the dissolution of Ukraine's current state and the withdrawal of NATO's expansion eastward.

But according to a former senior Kremlin official, the Russian president is prepared to compromise on territorial issues if he believes the other side has taken into account the"fundamental causes" of the war, writes the Financial Times.
