Russian forces do not fully control all the territory in the four regions and Russia has demanded that Ukraine pull out its troops from the parts of all four of them that they still control.
Ukraine says its troops still have a small foothold in Russia’s Kursk region a year after its troops crossed the border to try to gain leverage in any negotiations. Russia said it had expelled Ukrainian troops from Kursk in April.
Tatiana Stanovaya, a senior fellow at the Carnegie Russia Eurasia Center, described the current peace push as “the first more or less realistic attempt to stop the war”.
“At the same time, I remain extremely sceptical about the implementation of the agreements, even if a truce is reached for a while. And there is virtually no doubt that the new commitments could be devastating for Ukraine,” she said.
Fierce fighting is raging along the more than 1,000 km front line along eastern and southern Ukraine, where Russian forces hold around a fifth of the country’s territory.
Russian troops are slowly advancing in Ukraine’s east, but their summer offensive has so far failed to achieve a major breakthrough, Ukrainian military analysts say.
Ukrainians remain defiant.
“Not a single serviceman will agree to cede territory, to pull out troops from Ukrainian territories,” Olesia Petritska, 51, told Reuters as she gestured to hundreds of small Ukrainian flags in the Kyiv central square commemorating fallen soldiers.
