Explanation:

The North American Free Trade Agreement, NAFTA, was a treaty involving Canada, Mexico, and the United States, and having Chile as an associate, in a free-trade atmosphere, with reduced costs for the exchange of goods between the three countries.  

The former NAFTA came into force in 1992 and lasted until August 27, 2018, with a 15-year term with the customs barriers between the three countries. This regional trade in North America benefited the Mexican economy and helped it to face the competition represented by Japan and the European Union. Many Labor leaders agreed that NAFTA would only turn Canada and Mexico into US "colonies," increasing poverty in Mexico and worsening US unemployment because companies would move to Mexico and offer poor wages. Likewise, many environmental leaders believed that the industrial activity resulting from this agreement would greatly worsen the environmental conditions of these countries.
