The United States and Canada on Wednesday demanded dispute settlement talks with Mexico under a North American trade deal, charging that Mexican energy policies were discriminatory and "undermine" international firms and cross-border supplies.
The request, first announced by the U.S. Trade Representative's office, marks the most serious trade fight between Washington and Mexico City since the U.S.-Mexico-Canada Agreement on trade took effect two years ago. If unresolved, it could ultimately lead to punitive U.S. tariffs.
