The short version

Russia says it is establishing a security zone inside Ukraine along the border, describing it as protection for Russian border regions ¹².
The Kremlin says the planned zone would span 660 kilometres and that Russia controls about 70% of it, but it has not said how far the zone would extend into Ukraine ¹.
The area would involve parts of Ukraine’s Sumy and Kharkiv regions, which Russia is not claiming as its own territory, according to the Guardian ¹.
Putin says the zone is not open for discussion in future peace negotiations; that is Russia’s stated position, not an agreed settlement ¹².

What does Russia mean by a security zone?

Russia’s president, Vladimir Putin, says Russian forces are establishing a zone inside Ukraine along the countries’ border. He says the aim is to make Russia’s border regions safer. The statement does not set out a detailed plan for how the zone would work or what rules would govern it ¹².

The phrase “security zone” describes Russia’s stated purpose. It does not, on its own, tell readers where a boundary would be drawn, how deep the zone would reach, or whether the arrangement would be temporary. Those details are not provided in the available reports.

Where would the proposed zone be, and how large?

The Kremlin has put the zone’s length at 660 kilometres, and says about 70% of it is currently under Russian control. Those figures describe the length and claimed control of the zone; they do not tell us its depth inside Ukraine ¹.

The proposed area would include land in Ukraine’s Sumy and Kharkiv regions. The Guardian reports that these regions are not among the Ukrainian territories Russia is claiming as its own ¹. The available information does not provide a detailed map or exact boundaries.

Why does Russia say it is creating the zone?

Putin linked the plan to Ukraine’s incursion into Russia’s Kursk region in 2024–25. He said Russian forces had been tasked both with pushing Ukrainian forces out of Russian territory and establishing a zone in adjacent Ukrainian territory ¹².

That is Moscow’s explanation for its actions. The sources do not establish that creating such a zone would ensure the safety Russia says it seeks, or give an independent assessment of the military purpose or likely effect.

What could the zone mean for people in Ukraine?

For people in the affected parts of Sumy and Kharkiv, the immediate issue is that Russia says it intends to keep operating in territory inside Ukraine. The sources do not report how many people may be affected, what local conditions are, or whether there are plans for residents, services or property.

The announced length does not show how much land is involved or how close any particular community would be to military activity. Without a published depth, boundary map and practical arrangements, it is not possible to say precisely what the proposal would mean for individual residents.

Could the zone become part of a peace agreement?

Putin said Russia does not intend to make the zone a subject of potential peace negotiations with Ukraine. The Guardian describes it as non-negotiable from Russia’s point of view ¹².

That statement does not mean Ukraine or other parties have accepted the proposal, or that the zone’s status has been settled. The sources provided do not describe an agreement on the zone or explain how the two countries might address it in any future talks.

What we don't know yet

How deep the zone would extend into Ukraine and where its boundaries would be.
What military or administrative arrangements Russia intends to use in the area.
How many residents or communities could be affected and what protections, if any, would apply.
Whether Ukraine or any other party will address the proposal in future negotiations.
