For the first time, the United States has sensed Russia's real willingness to end the war, Reuters sources say.
According to an unnamed US official, both Ukraine and Russia are now privately demonstrating their willingness to compromise on the territorial issue.
The source said the US was cautiously optimistic about possible progress.
The interlocutor also said that one of the main topics of the future negotiations in Abu Dhabi will be security guarantees for Ukraine.
On November 9, the head of the Ukrainian negotiating team, Rustam Omirov, announced that the Ukrainian delegation had left for Abu Dhabi. Before the tripartite meeting, American representatives also plan to hold talks with European officials.
