Trilateral peace talks between Russia, Ukraine and the United States concluded in Abu Dhabi on Saturday, with no immediate breakthrough. Further rounds are expected next week as tensions continue, particularly over Russia’s demand for Ukraine’s Donbas region.

President Volodymyr Zelensky of Ukraine said that rare three-way negotiations between Ukrainian, Russian and American teams in Abu Dhabi had been “constructive.”

Abu Dhabi hosts trilateral meeting with the U.S., Ukraine and Russia in a possible sign that the nearly four-year war could be coming to an end.
