Why the Donbas remains the core obstacle to a Russia-Ukraine peace deal

After weeks of high-level diplomacy, Russia and Ukraine remain locked in a familiar dead end: territory. Despite renewed pressure from international mediators, both sides are refusing to shift on the future of the Donbas, the industrial eastern region that has shaped the war’s trajectory since 2014. Moscow insists that any settlement must formalise its control over all of Donetsk and Luhansk, including the roughly 2,500 square miles of land it still does not hold. Kyiv, in turn, says that ceding territory is unacceptable and would reward aggression. The dispute has become the central barrier to progress at a time when battlefield momentum, political fatigue and international impatience are reshaping the conflict, the New York Times reported.

Why the remaining Ukrainian-held pocket matters

The area Russia seeks lies in the heart of Donetsk. It includes Sloviansk and Kramatorsk, cities that have served as Ukraine’s military and administrative hub since separatist fighting erupted more than a decade ago. More than 200,000 civilians still live there, and the region is among the most heavily fortified in Ukraine. For Kyiv, relinquishing these cities would mean surrendering both symbolic ground and a critical defensive anchor. For Moscow, absorbing the rest of Donbas is central to its justification for the war and to President Vladimir V Putin’s repeated insistence that Russia must “liberate” historically Russian-speaking regions. Control of these cities would also give Russia greater security over the territory it already occupies in Luhansk and southern Donetsk.
