[U.S. officials say the U.S. is “cautiously optimistic” about Russia-Ukraine talks in Abu Dhabi] November 10, according to a report from the U.S. Axios news website on the 9th, the U.S. government is “cautiously optimistic” about the upcoming peace talks between Russia and Ukraine in Abu Dhabi, the capital of the United Arab Emirates. An anonymous U.S. official told the media that day: "We have an opportunity to make significant progress in reaching an agreement... As a mediator, we are seeing positive signs." The official also said that Russia and Ukraine have "showed some flexibility" on territorial issues in recent weeks, but it is impossible to reach a consensus on territorial issues before reaching a security agreement.
