MEXICO CITY (Reuters) - Mexico’s President Andres Manuel Lopez Obrador said on Thursday he was confident the United States-Mexico-Canada-Agreement would be ratified, increasing trade in the North American region.

The USMCA deal, negotiated last year, faces opposition by some Democrats in the U.S. Congress who want assurances that labor and environmental rules will be enforceable. It must be passed in the three countries’ legislatures before becoming law.
