The U.S. is currently engaged in trade negotiations with Mexico under the United States-Mexico-Canada Agreement (USMCA), according to U.S. Trade Representative Jamieson Greer. According to Jin10, Greer noted in an interview with Fox Business Network that discussions with Canada have proven more challenging. He highlighted that negotiations concerning the Gordie Howe International Bridge, which connects Detroit, Michigan, and Windsor, Ontario, are being conducted separately. U.S. President Donald Trump recently threatened to halt the opening of this $4.7 billion bridge, marking his latest move in addressing trade issues with Canada.
