Russian President Vladimir Putin told the Trump administration earlier this week that he would end the war with Ukraine in exchange for the region in eastern Ukraine known as the Donbas, The Wall Street Journal reported on Friday.

The WSJ cited European and Ukrainian officials, who were briefed by Trump and his special envoy, Steve Witkoff, on discussions with Putin. Putin reportedly made the offer to Witkoff during their meeting in Moscow on Wednesday.

Russia wants full control of Ukraine’s Donetsk and Luhansk regions, along with the Crimean Peninsula that Russia annexed in 2014. Russian forces are now mostly in control of Donetsk and Luhansk, but Ukrainian troops are still fighting back in some areas in the regions.

European officials told the WSJ that they were concerned over Putin’s proposal, saying that it could be the Russian dictator’s way of avoiding punishment from Trump, who is expected to impose secondary tariffs on Russia. European leaders also questioned whether Putin would be willing to give up fighting for Ukraine’s Zaporizhia and Kherson regions, which are southwest of Donetsk and Luhansk.

Trump said at the White House on Friday that a summit with Putin is in the works, and a location for talks has been decided upon. He added that he will confirm details of the meeting later on Friday. Some of Trump’s stipulations for the summit included that no European leaders be present and that Putin agree to also meet with Zelensky.

“Putin, I believe, wants to see peace, and [Ukrainian President Volodymyr] Zelensky wants to see peace,” he said.

The president added that there would be “some swapping” of territories between Russia and Ukraine.

“It’s very complicated, but we’re going to get some back and we’re going to get some switched … to the betterment of both,” he added.

Trump’s deadline for Russia to reach a peace deal with Ukraine ended on Friday, unless he agrees to extend it, with a summit between Putin and Zelensky appearing more likely. Asked whether the deadline was still firm, Trump replied, “We’re going to see what [Putin] has to say. It’s going to be up to him.”

The president ramped up the pressure on Putin to end the conflict, which has resulted in an estimated hundreds of thousands of deaths over the past three years, as Putin continued to launch drone and missile attacks targeting Ukrainian civilian centers. Last week, Trump also repositioned two nuclear submarines after former Russian President Dmitry Medvedev threatened that Trump’s ultimatums to Putin were a “step towards war.”
