The North American Free Trade Agreement (NAFTA) is an example of a multilateral agreement. It was ratified in the U.S.-Canada trade agreement when Mexico joined the previous trade agreement. In September 2018, the Trump administration successfully concluded new negotiations with Mexico and Canada that lasted more than a year. These negotiations included raising auto industry wages for workers in Mexico and changing pharmaceutical regulations with Canada. The North American Free Trade Agreement (NAFTA) is a trade agreement between the United States, Canada and Mexico, with the goal of abolishing tariffs between countries and promoting all aspects of international trade. Opponents of NAFTA point out that pollution in Mexico is largely a free asset and that freedom pollution provides an economic advantage to Mexican industries over those of the United States and Canada. Is there anything that can tell us a fair solution to this problem while protecting the environment we all share? What is this solution? There are many arguments for and against the contract. One of the arguments against the fact that the Mexican industry is not obliged to comply with the same environmental standards as the industries of the United States and Canada. The United States and Canada have intervened in the market and have attempted to internalize some of the cost of pollution by adopting rules on the amount of pollutants that industries can emit.
