The first day of trilateral negotiations between Russia, Ukraine and the United States has concluded in Abu Dhabi, the capital of the United Arab Emirates, after four and a half hours of discussions.

The meeting began at 11:12 a.m. Moscow time and included a break lasting approximately 40 minutes. Most of the negotiations took place behind closed doors, with journalists excluded from the discussions.

Media reports indicated that members of the Russian and Ukrainian delegations communicated in Russian during the meeting.

US Secretary of State Marco Rubio described the first day of talks as highly productive in comments to Reuters. However, he acknowledged that considerable work remains before the parties can reach final agreements.

Security guarantees and the future structure of European security were among the central issues discussed on November 10. The delegations also addressed the possibility of a large-scale prisoner exchange between Russia and Ukraine.

The next round of negotiations is scheduled for November 11. According to Politico, the delegations intend to address territorial disputes as part of the continuing discussions.
