Ukraine’s latest peace plan proposes a demilitarized “free economic zone” in the Donbas region where American business interests could operate — an attempt to bring US President Donald Trump on board, according to two people familiar with the matter, Politico reports.

Trump, who sounded skeptical about the prospects for a breakthrough in Oval Office comments on Wednesday, “is aware of” the latest 20-point plan Ukraine sent to the White House Wednesday, White House spokesperson Karoline Leavitt said Thursday.

The document is expected to be discussed by the United States, Ukraine, France, Germany, and the United Kingdom.

The two people familiar with the proposal, granted anonymity because they were not authorized to speak with the press, both expressed skepticism that Russia would back the plan, crafted this week with input from European leaders. Trump, they suggested, still views Ukraine as the weaker, more malleable party in the conflict, especially in the wake of a corruption scandal that forced Ukrainian President Volodymyr Zelenskyy’s longtime chief of staff, Andriy Yermak, to step down.

“The White House is using this latest corruption scandal to pressure Zelenskyy,” one of the people said. 

Until now, Russian President Vladimir Putin has demanded that Ukraine withdraw its troops from Donbas to end the war. He also stated that this region is historically part of Russia and that Moscow will reclaim it by military or other means.
