Vladimir Putin is demanding that Ukraine give up all of the eastern Donbas region, renounce ambitions to join NATO, remain neutral and keep Western troops out of the country, three sources familiar with top-level Kremlin thinking told Reuters.

Vladimir Putin has played his hand and has told his generals what he needs in return for bringing the Ukraine invasion that has killed hundreds of thousands to an end, according to sources.

Ukrainian President Volodymyr Zelenskyy rejects Russian President Vladimir Putin's demands to cede the Donbas region, citing sovereignty concerns and the area's economic and strategic importance.

Ukraine’s President Volodymyr Zelensky vowed on Tuesday not to give eastern Ukrainian land to Russia, saying that abandoning the Donbas region would open the door for Russian President Vladimir Putin to “start a third war” in Ukraine.

Erdogan also told Putin he was closely following developments related to the process, and that Turkey had strived for a just peace since the beginning of the war, it said.
