Putin Alaska summit while European Commission and NATO leaders emphasize any deal must protect Ukraine's long-term security interests.

Touching on Ukrainian anxieties that a direct meeting between Mr. Trump and Putin could marginalize Kyiv and European interests, Zelenskyy said: "Any decisions that are without Ukraine are at the same time decisions against peace. They will not bring anything. These are dead decisions. They will never work."

Ukrainian President Volodymyr Zelenskiy won diplomatic backing from Europe and the NATO alliance on Sunday ahead of a Russia-U.S. summit this week where Kyiv fears President Vladimir Putin and President Donald Trump may try to dictate terms for ending the 3-1/2-year war.

Earlier in the day, Zelenskyy dismissed the planned Trump-Putin summit, scheduled for Friday in Alaska, warning that any negotiations to end Europe’s biggest conflict since World War II must include Kyiv.

Ukraine’s President Volodymyr Zelenskyy declared Saturday that his countrymen “will not give their land to occupiers,” after President Donald Trump suggested that a peace deal would include some “swapping” of territories with Russia.
