The Mexican government told the U.S. that it’s ready to work with the Biden administration to draw up a plan to remedy the denial of workers’ rights at a General Motors Co. pickup-truck plant in central Mexico.

President Andres Manuel Lopez Obrador’s administration sent its response last Friday, ahead of the end of a 45-day window for the nation to answer to a U.S. complaint under the U.S.-Mexico-Canada trade agreement, according to people familiar with the case, who asked not to be identified because they weren’t authorized to speak publicly about the case.
