LONDON — Ukraine and key European nations demanded a role in any negotiations to end Russia’s war on the country, after President Donald Trump unilaterally announced an immediate start to direct peace talks with President Vladimir Putin after speaking with the Russian leader by phone.

Trump said in a post to social media on Wednesday that he spoke with Putin, adding the two leaders “agreed to have our respective teams start negotiations immediately” to end the fighting in Ukraine after nearly three years of Russia’s full-scale invasion.

Moscow launched its attack in February 2022 with the aim of toppling Zelenskyy’s government in Kyiv and annexing swaths of the country. The “special military operation” — as the Kremlin termed the invasion — expanded on Moscow’s annexation of Crimea and its fomentation of, and active military support for, separatist rebellion in parts of eastern Ukraine in 2014.

“I think we’re on the way to getting peace,” Trump said. The president did not clarify whether Ukraine and its President Volodymyr Zelenskyy would be directly involved in any peace talks. Excluding Kyiv would align with Putin’s repeated demand that Ukraine be sidelined, the Russian leader having dismissed Zelenskyy as “illegitimate.”

Kyiv’s omission from negotiations would represent a striking break from years of U.S. and allied policy, which under former President Joe Biden was guided by the “nothing about Ukraine without Ukraine” principle, with the former president also refusing to speak directly with Putin while the war continued.

Trump spoke with Zelenskyy after his phone call with Putin. The Ukrainian leader said in a post to social media that the two discussed “opportunities to achieve peace, discussed our readiness to work together at the team level, and Ukraine’s technological capabilities — including drones and other advanced industries.”

Trump also said he would meet with Putin in Saudi Arabia, though did not set a date.

Addressing the conversation, Trump said on Truth Social that Zelensky,”like President Putin, wants to make PEACE.”

Trump separately hinted at the expiry of Zelenskyy’s presidential term. Ukraine was due to hold presidential elections last year, but the vote was delayed as the country is still under martial law as a result of Russia’s invasion. At “some point you’re going to have an election,” Trump said.

Ukraine and American allies in Europe were quick to call for a unified negotiating front.

“We are looking forward to discussing the way ahead together with our American allies,” said a joint statement from the foreign ministers of France, Germany, Poland, Italy, Spain, the U.K., Ukraine, the European Union’s European External Action Service and the European Commission.

“Our shared objectives should be to put Ukraine in a position of strength,” the statement added. “Ukraine and Europe must be part of any negotiations.”

Kaja Kallas, the EU’s foreign affairs chief, said on X, “Ukraine’s independence and territorial integrity are unconditional.”

Trump said a meeting between Zelenskyy, Vice President JD Vance and Secretary of State Marco Rubio was scheduled during the weekend Munich Security Conference event in Germany.

The State Department said that Ukraine-Russia envoy Keith Kellogg will begin a 10-day visit to Germany, Belgium and Ukraine on Thursday.

Trump’s announcement of direct D.C.-Moscow talks came shortly after Defense Secretary Pete Hegseth told allies in Belgium that Ukraine cannot liberate all territory occupied by Russian forces and will not be given NATO security protection as part of any peace deal.

“The bloodshed must stop and this war must end,” Hegseth said. His address was the most detailed delineation of the Trump administration’s desired peace deal since the president returned to the Oval Office.

Pro-talk signals from the U.S. raised concerns in Ukraine and abroad that Kyiv will be forced into territorial and political concessions in exchange for an end to the fighting.

John Bolton — Trump’s former national security adviser — for example, said on X that the president’s approach is tantamount to a “sell out” of Ukraine. “Trump has effectively surrendered to Putin on Ukraine.”

“It’s a bad sign that he has talked first to Putin, not to Zelenskyy,” Oleksandr Merezhko — a member of the Ukrainian parliament and the chair of the body’s foreign affairs committee — told ABC News.

“Such a phone call is in itself a reward for Putin,” he added. “It’s sort of a break in his political isolation.”

Still, Merezhko said Trump’s approach does “not quite” mean a total exclusion of Ukraine. “The principle ‘nothing about Ukraine without Ukraine’ is more about not taking decisions without Ukraine which have influence upon Ukraine,” he said.

Pressure for peace is building within and without. A Gallup poll published in November indicated that most Ukrainians favored a rapid end to the devastating war. Zelenskyy’s public rhetoric largely reflects this sentiment, though the president has warned that no peace deal is sustainable without concrete U.S. security guarantees.

“This war of attrition is only going to make us weaker,” Iuliia Mendel — Zelenskyy’s former press secretary — told ABC News. “For a long time, Ukraine has been at the stage when negotiations are urgent to save the nation.”

The Kremlin confirmed that Trump had spoken with Putin.

“The topic of a settlement in Ukraine was discussed,” spokesperson Dmitry Peskov told reporters after the call on Wednesday.

“President Trump spoke in favor of an early end to hostilities and a peaceful solution to the problem,” he added. “President Putin, for his part, mentioned the need to eliminate the root causes of the conflict and agreed with Trump that a long-term settlement can be achieved through peaceful negotiations.”

On Thursday, Peskov told reporters that Moscow had begun preparing a negotiating group to organize a meeting between Trump and Putin. “Definitely started. And as the president makes the appropriate decisions, we will inform you,” Peskov said.

When asked if a visit by U.S. representatives to Moscow is expected in the near future, Peskov said: “Not yet. So far, there are no specific agreements in this regard.”

Both Moscow and Kyiv are maneuvering for leverage in preparation for revived talks. This week, Russia and the U.S. concluded a prisoner swap described by Trump as a goodwill gesture that could help advance peace talks.

Zelenskyy, meanwhile, met with Treasury Secretary Scott Bessent in Kyiv to discuss a potential deal to secure U.S. access to hundreds of billions of dollars worth of Ukrainian minerals.

Russian and Ukrainian leaders have both expressed readiness to resume negotiations, though neither side has indicated willingness to make significant concessions.

This week, Zelenskyy suggested Ukraine would be ready to give up territory it seized in Russia’s western Kursk region in exchange for the liberation of some Ukrainian territory occupied by Moscow’s troops.

Peskov dismissed the idea as “impossible” at a Wednesday briefing with journalists. “Russia has never discussed an exchange of its territories and never will,” Peskov said.

“Naturally, Ukrainian units will be ousted from this territory. Everyone who is not eliminated will be ousted,” Peskov added.
