The North America Free-Trade AGREEMENT is an agreement among North American countries. The US government benefits from this agreement because it expands the market for American PRODUCTS by giving American EXPORTERS easy access to North American markets.
The North American Free Trade Agreement (NAFTA) is a free trade zone between Canada, the United States and Mexico. The Treaty allows reducing costs to promote the exchange of goods between the three countries.
Unlike the European Union, NAFTA does not create a set of supranational governmental bodies or a body of laws above the national laws of each country. NAFTA is a treaty under international law. Under the laws of the United States, it is classified as an executive agreement of Congress, reflecting a peculiar sense of the term "treaty" in the constitutional law of the United States, where it is not subject to the practices of international law or subject to the laws of other nations.
