The United States has warned that it might stop sharing intelligence and supplying weapons to Ukraine to push Kyiv towards accepting the outline of a peace deal created by Washington, two people familiar with the situation said. Washington has given Ukraine a 28-point proposal that endorses some of Russia’s key demands, including asking Kyiv to give up more territory, reduce its military, and remain blocked from joining NATO.

The unnamed sources said Kyiv was facing stronger pressure from Washington than in any earlier peace talks, and that the United States wanted Ukraine to sign the framework by next Thursday.

A group of senior United States military officials met President Volodymyr Zelenskiy in Kyiv on Thursday. The United States ambassador in Ukraine and the army public affairs chief described the talks as successful and said Washington wanted an “aggressive timeline” for signing a document between the two countries.

Zelensky spoke by phone on Friday with the leaders of Britain, Germany and France and appeared careful not to openly reject the plan. “We value the efforts of the United States, President Trump, and his team aimed at ending this war. We are working on the document prepared by the American side. This must be a plan that ensures a real and dignified peace,” he said.

European leaders, who were not included in discussions about the 28-point plan, showed strong support for Kyiv. Europe’s own plan had only two points, said the EU foreign policy chief, Kaja Kallas: weaken Russia and support Ukraine.

United States officials defended their proposal and said it was created after talks with Rustem Umerov, secretary of Ukraine’s National Security and Defence Council. A senior United States official said Umerov agreed to most of the plan after making changes and presented it to Zelensky.

However, Umerov denied approving any part of the plan. “During my visit to the United States, my role was technical — organising meetings and preparing the dialogue. I provided no assessments or, even more so, approvals of any points. This is not within my authority and does not correspond to the procedure,” he wrote on Telegram. He later said Kyiv would not accept any plan that violates its sovereignty.

The Kremlin said Russia had not received any official information about the plan. Kremlin spokesman Dmitry Peskov said Kyiv should make a “responsible decision” soon.

The plan seen by Reuters includes conditions that Ukrainian officials have previously rejected as surrender. It would force Ukraine to pull back from areas it still controls in eastern regions that Russia claims to have annexed, while Russia would give up smaller areas it holds elsewhere. Ukraine would be permanently blocked from joining NATO, its armed forces would be limited to 600,000 troops, and NATO would agree not to station troops there.

Sanctions on Russia would be slowly removed, Moscow would return to the G8, and frozen Russian assets would be placed into an investment fund with Washington receiving part of the profits. Ukraine’s demand for binding security guarantees is mentioned only briefly with no explanation.

Trump, who returned to office this year promising to end the war quickly, has acknowledged some of Russia’s reasons for its 2022 invasion while also showing frustration with Moscow. Last month, he cancelled a planned summit with Vladimir Putin and placed sanctions on Russia’s two main oil companies.

The push for diplomacy comes as Ukrainian forces struggle on the battlefield and Zelensky’s government faces a corruption scandal. Parliament dismissed two cabinet ministers on Wednesday. Russian forces now control almost one-fifth of Ukraine and are slowly advancing along a 1200 km front. Russia claims to have taken Kupiansk and most of Pokrovsk, while Kyiv denies losing the cities but admits Russia is advancing.
