Russia and Ukraine reached a preliminary agreement on a large-scale prisoner exchange during US-mediated talks in Abu Dhabi on November 10-11, 2026, marking their first negotiations in nine months. Officials described the planned swap as potentially the largest of the conflict, involving 1,000 or more personnel per side, with details to be finalized shortly and execution expected within two to three weeks. This builds on the most recent exchange of 270 prisoners each on October 23, 2026. Prisoner swaps remain one of the few consistent channels of cooperation amid stalled progress on ceasefires and territorial issues. US envoys plan follow-up meetings in Moscow and with Ukrainian leadership to advance implementation, though broader diplomatic gaps persist.
