Why was Ukraine not represented at the meeting between U.S. and Russia in Saudi Arabia?

The transcript indicates that Ukrainian officials were notably absent from the high-level meeting between the United States and Russia held in Saudi Arabia. Despite the meeting's focus on ending the war in Ukraine, there were no representatives from Kyiv present at these diplomatic talks. This absence raises significant concerns about the legitimacy and effectiveness of negotiations conducted without Ukrainian participation. The lack of Ukrainian representation is particularly notable given that the primary agenda item was finding a resolution to the ongoing conflict directly affecting their nation.
