After Democrats in the U.S. threatened to hold up a renegotiated Nafta, Mexico’s ruling party beefed up a labour bill to meet requirements laid out in the trade deal and plans to vote it through this month. The bill now satisfies “diverse obligations” required by the United States-Mexico-Canada Agreement, or USMCA, as the new Nafta deal is known, said Mario Delgado, the majority leader for Mexico’s lower house. The lower house could vote on it in a week’s time, he told reporters Thursday.
