European officials were reported to have presented their own Ukraine peace proposals to the United States on Saturday (Aug 9) as President Donald Trump prepared for talks with Russian President Vladimir Putin on ending the war.

Trump announced on Friday that he would meet Putin in Alaska on Aug 15, saying the parties, including Ukrainian President Volodymyr Zelenskyy, were close to a deal that could resolve the three-and-a-half-year conflict.

Details of the potential deal have yet to be announced, but Trump said it would involve "some swapping of territories to the betterment of both". It could require Ukraine to surrender significant parts of its territory - an outcome Kyiv and its European allies say would only encourage Russian aggression.

US Vice President JD Vance met Ukrainian and European allies in Britain on Saturday to discuss Trump's push for peace.

The Wall Street Journal reported that European officials had presented a counter-proposal, which included demands that a ceasefire must occur before any other steps are taken and that any territory exchange must be reciprocal, accompanied by firm security guarantees.

"You can't start a process by ceding territory in the middle of fighting," it quoted one European negotiator as saying. European officials contacted by Reuters were unable to confirm the report.

Zelenskyy said the meeting was constructive. "All our arguments were heard," he said in his evening address to Ukrainians.

"The path to peace for Ukraine should be determined together and only together with Ukraine; this is key principle," he said.

He had earlier rejected any territorial concessions, saying "Ukrainians will not give their land to the occupier".

The Trump administration is considering inviting Zelenskyy to join the US and Russian presidents at their Alaska meeting, NBC News reported, citing an unnamed US official.

Trump is open to holding a trilateral summit in Alaska with Putin and Zelenskyy, a White House official said on Saturday.

However, the White House is currently planning a bilateral meeting with Putin at his request, the official added.

French President Emmanuel Macron also said Ukraine must play a role in any negotiations.

"Ukraine's future cannot be decided without the Ukrainians, who have been fighting for their freedom and security for over three years now," he wrote on X after what he said were calls with Zelenskyy, German Chancellor Friedrich Merz and British Prime Minister Keir Starmer.

"Europeans will also necessarily be part of the solution, as their own security is at stake."
