Mexico’s Economy Ministry has accepted a U.S. request to probe alleged labor abuses at a Panasonic (6752.T) auto parts plant in the northern border city of Reynosa, it said on Monday.

The request from the U.S. Trade Representative (USTR) earlier this month marked the third U.S. labor complaint under a new trade deal that aims to improve workplace conditions in Mexico.

Mexico’s Economy Ministry said it sent its response on Thursday and will review the case with the Labor Ministry to determine if worker rights had been violated under the 2020 United States-Mexico-Canada Agreement (USMCA).
