Why is President Zelensky furious about the talks in Saudi Arabia?

President Volodymyr Zelensky is furious about being excluded from crucial negotiations between US and Russian officials in Saudi Arabia regarding the ongoing war in Ukraine. He has canceled his scheduled trip to Saudi Arabia in protest of these talks being held without Ukrainian participation. Zelensky is particularly upset because these negotiations directly concern the conflict in his country, yet Ukraine has been left out of the discussion process. He believes that meaningful solutions to the war cannot be achieved without Ukraine's direct involvement in peace talks, highlighting the problematic nature of major powers discussing Ukraine's future without its representation.
