MEXICO CITY, April 20 (Xinhua) -- Formal negotiations to review the United States-Mexico-Canada Agreement (USMCA) are expected to begin the week of May 25, Mexican Economy Minister Marcelo Ebrard said Monday.

Speaking after meeting U.S. Trade Representative Jamieson Greer in Mexico City, Ebrard said both sides are outlining their main concerns ahead of the next phase of talks.

"With that, we would move to formal negotiations. We estimate they will start the week of May 25," he said.
