Russian President Vladimir Putin announced Thursday that Russian forces are actively establishing a “security buffer zone” along the Russia–Ukraine border, a move that has drawn immediate criticism from Kyiv and international observers as a further escalation in the ongoing conflict.

“I have already said that a decision was made to create the necessary security buffer zone along the border. Our armed forces are currently solving this problem,” Putin said during a government meeting in Moscow. He added that Ukrainian firing positions are being actively suppressed as part of the effort.

Putin’s remarks follow earlier indications from March when he visited Russia’s Kursk region, an area that had previously seen Ukrainian advances. During that visit, Putin discussed potential restoration work and was reportedly asked by local officials to consider a buffer zone extending into Ukraine’s Sumy region.

Putin said the plan aims to restore destroyed infrastructure and allow civilians to safely return to their homes in areas near the frontlines. He is expected to host a dedicated meeting on rebuilding and stabilization efforts in border areas, according to Russian state media.

Ukrainian and International Response

The announcement was swiftly condemned by Ukraine. Foreign ministry spokesperson Heorhii Tykhyi labeled the move as “aggressive”, saying it demonstrates that “Russia is the obstacle to peace efforts now.” Kyiv has consistently rejected any unilateral attempts by Moscow to annex or alter its internationally recognized borders.

The development comes just ahead of a major prisoner exchange between Ukraine and Russia, expected on Friday, following last week’s landmark direct talks in Turkey — the first formal negotiations between the two sides in three years. The agreement includes the exchange of 1,000 prisoners from each side.

Kremlin spokesperson Dmitry Peskov confirmed Thursday that Russia has received Ukraine’s proposed list for the exchange. Ukrainian President Volodymyr Zelensky said on X that his government is verifying “the details for each individual included on the lists submitted by the Russian side.”
