Officials from Europe, the United States and Ukraine gathered in Geneva on Sunday to discuss a draft plan presented by Washington to end the Ukraine war, after Kyiv and its allies voiced alarm over what they saw as major concessions to the aggressor Russia.

On Friday, U.S. President Donald Trump said Ukrainian President Volodymyr Zelenskyy had until Thursday to approve the 28-point plan, which calls on Ukraine to cede territory, accept limits on its military and renounce ambitions to join NATO.

For many Ukrainians, including soldiers fighting on the front lines, such terms would amount to capitulation after nearly four years of fighting in Europe’s deadliest conflict since World War II.

Since the plan was announced, there has been considerable confusion about who was involved in drawing it up. European allies said they had not been consulted.

A U.S. official said U.S. Special Envoy Steve Witkoff and Secretary of State Marco Rubio had arrived on Sunday for the talks on ending Russia’s full-scale invasion.
