US-mediated talks in Abu Dhabi concluded with Russia and Ukraine reaching a preliminary agreement on a large-scale prisoner exchange, potentially involving more than 1,000 individuals per side—the largest such swap since early 2025. This followed an October 23 exchange of 270 prisoners each and reflects continued bilateral cooperation on humanitarian issues amid stalled progress on territorial and security matters. US envoys have indicated the swap could occur within two to three weeks, with details still under finalization. Ongoing negotiations and any follow-up diplomatic steps in the coming weeks remain key factors that could influence the timing and scale of the next exchange.
