Axios reported the information.According to Ukrainian officials, the current U.S.-backed peace plan has shifted in Moscow's favor following recent high-level meetings between Trump advisers and Russian leader Vladimir Putin. The proposal centers on two contentious issues: Russia's insistence that Ukraine surrender the entire Donbas region, including areas not under Russian military control, and Ukraine's demand for robust American security guarantees to deter future aggression.The tension came to a head during a two-hour phone call on Saturday between Zelenskyy and Trump advisers Steve Witkoff and Jared Kushner, following their five-hour Kremlin meeting with Putin. "It felt like the U.S. was trying to sell us in different ways the Russian desire to take the whole of Donbas and that the Americans wanted Zelenskyy to accept all of it in the phone call," a Ukrainian official said.The call followed three days of negotiations in Miami between Trump's team and Zelenskyy's advisers, which produced limited progress. Zelenskyy reportedly told the American officials he had received the proposal only an hour before the call and hadn't reviewed it, prompting President Trump to express disappointment publicly and claim that Zelenskyy's negotiators "love" the U.S. plan while Russia was "fine" with it.Ukrainian officials dispute the characterization, noting that the updated proposal contained harsher terms on territorial control and the Zaporizhzhia nuclear power plant, while leaving critical questions about security guarantees unanswered. "There are major things about territory which need to be discussed more: Who controls what, who stays where, who withdraws and if Ukraine withdraws from the contact line, how to make sure that Russia does the same and [doesn't continue] with the fighting," the official explained.As diplomatic pressure mounted, Zelenskyy embarked on a European tour this week, meeting with leaders from the United Kingdom, France, and Germany in London on Monday. The European powers offered strong backing, with German Chancellor Friedrich Merz stating he was "skeptical of some of the details that we see in the documents coming from the U.S. side," while French President Emmanuel Macron declared, "We have a lot of cards in our hands."The Trump administration views Zelenskyy's European consultations as a delaying tactic, while Ukrainian officials counter that they feel Washington is attempting to isolate their president from key allies to increase leverage. The Europeans are counseling patience and caution, creating friction with White House officials who see their involvement as an impediment to reaching an agreement.Zelenskyy addressed the impasse during a Monday briefing with reporters: "Russia insists that we give up territory. We do not want to give anything up. That is exactly what we are fighting for. The Americans are currently looking for a compromise." He announced that Ukraine and European partners would submit a counter-proposal to the U.S. on Tuesday.The standoff reflects deepening mistrust between the Zelenskyy and Trump administrations despite extensive negotiations. Ukrainian officials maintain that while some framework for security guarantees has been proposed, it falls short of the Senate-ratified treaty they seek and lacks clarity on America's enforcement role and European responsibilities.On December 9, Volodymyr Zelenskyy said that the draft peace plan has been shortened from 28 to 20 points. Ukraine and Europe will work together on its final version, after which the document will be sent to the U.S.
