Abu Dhabi: 4.5 hours of talks, FSB agent in the room, and changes to Ukraine's borders. What else?

The first day of trilateral talks involving Russia, Ukraine, and the USA in Abu Dhabi lasted about four and a half hours. Negotiations are set to resume on Wednesday. Reports suggest the USA may propose changes to the administrative borders of Ukrainian regions partially occupied by Russia, which could allow Moscow to claim full control without formally transferring territory. This proposal faces opposition from both Kyiv and European capitals. The discussions also focused on security guarantees for Ukraine and Europe, with Ukraine insisting that any talks on a new security architecture must occur after the war ends. Additionally, a significant agreement was reached regarding a large-scale prisoner exchange, although details remain undisclosed.
