What does President Zelensky believe is critical for any negotiations to end the war in Ukraine?

President Zelensky firmly believes that transparency and inclusion are essential for any negotiations aimed at ending the war in Ukraine. During his visit to Turkey (after canceling a trip to Saudi Arabia), he emphasized that peace talks should not occur 'behind the backs' of those most affected. Zelensky specifically stated that for Ukraine, their region, and Europe, it is critical that negotiations involve all stakeholders directly. His concern appears to be that diplomatic discussions between major powers like the U.S. and Russia might proceed without adequate Ukrainian participation, potentially undermining Ukraine's interests in any peace settlement.
