Kyiv. Ukrainian President Volodymyr Zelensky said Tuesday that Russian President Vladimir Putin wants Ukraine to withdraw from the remaining 30 percent of the Donetsk region that it controls as part of a ceasefire deal, a proposal the leader categorically rejected.

Zelensky reiterated that Ukraine would not withdraw from territories it controls, saying that would be unconstitutional and would serve only as a springboard for a future Russian invasion.

He said diplomatic discussions led by the United States focusing on ending the war have not touched on security guarantees for Ukraine to prevent future Russian aggression and that meeting formats currently being discussed do not include Europe’s participation, both key demands of Kyiv.

Zelensky said the necessity of territorial concessions was conveyed to him by US officials ahead of a summit Friday between US President Donald Trump and Russian President Vladimir Putin, and in further meetings at the level of national security officials.

It remained unclear whether Ukraine would take part in the Friday summit. European Union leaders also have been sidelined from the meeting, and they appealed to Trump on Tuesday to protect their interests.

Ukraine Will Not Withdraw from the Donbas
Zelensky said Putin wants the remaining 9,000 square kilometers (3,500 square miles) of Donetsk under Kyiv’s control, where the war’s toughest battles are grinding on, as part of a ceasefire plan.

Doing so would hand Russia almost the entirety of the Donbas, a region comprising Ukraine’s eastern industrial heartland that Putin has long coveted.

Zelensky learned of Russia's position after holding a call with Trump and special envoy Steve Witkoff, after the latter’s bilateral meeting with Putin. Witkoff told Zelensky that Russia was ready to end the war and that there should be territorial concessions from both sides. Some European partners were also part of the call.

“And that, probably, Putin wants us to leave Donbas. That is, it didn’t sound like America wants us to leave,” he said, recounting the call.

Zelensky reiterated that withdrawing from Ukraine-controlled territory was out of the question, especially as the question of security guarantees for Ukraine, were not being discussed.

“We will not leave Donbas. We cannot do this. Everyone forgets the first part - our territories are illegally occupied,” Zelensky told reporters at a briefing on Tuesday. “Donbas for the Russians is a springboard for a future new offensive."

Zelensky said this is what occurred in 2014 when Russia illegally annexed the Crimean Peninsula.

Seeking Trump’s Ear before the Summit
Trump has said he wants to see whether Putin is serious about ending the war, now in its fourth year.

The US president has disappointed allies in Europe by saying Ukraine will have to give up some Russian-held territory. He also said Russia must accept land swaps, although it was unclear what Putin might be expected to surrender.

The Europeans and Ukraine are wary that Putin, who has waged the biggest land war in Europe since 1945 and used Russia’s energy might to try to intimidate the EU, might secure favorable concessions and set the outlines of a peace deal without them.

Referring to the format for ceasefire talks, Zelensky said that the US proposed a bilateral meeting, between the US and Russia, and then a trilateral meeting that would include Ukraine. Zelensky said the presence of Europe was important for Kyiv because these were the only partners offering security guarantees, including funding the Ukrainian army.
