The United States and Canada have told Mexico they could reach a compromise within 48 hours on keeping the updated North American Free Trade Agreement a three-country deal, the Mexican economy minister said Friday. Speaking as he presented the Mexican Senate with the current US-Mexican agreement to update NAFTA — which does not include Canada, the third member of the original deal — Economy Minister Ildefonso Guajardo said Washington and Ottawa were making a “very serious,” last-ditch attempt to bridge their differences.
