MEXICO CITY (AP) — Mexico’s economy secretary has proposed yet another round of talks with the United States on a dispute over Mexico’s energy sector. Mexico hopes to stave off a full-fledged trade complaint under the U.S.-Mexico-Canada trade agreement. The United States says Mexico is unfairly favoring its state-owned electricity and oil companies over American competitors and clean-energy suppliers. U.S. Trade Representative Katherine Tai appears willing to keep talking, but her office says she “underscored the urgency of prompt and meaningful progress” at a Thursday meeting. The two countries also appear headed for another commercial dispute over a Mexican ban on imports of genetically modified yellow corn.
