NAFTA was signed in 1993 by the US, Canada, and Mexico to create a free trade area with no trade barriers or tariffs between the countries. The goals of NAFTA were to allow free movement of goods and services, promote competition, protect property rights, and resolve disputes among members. While NAFTA increased trade, profits, and economic cooperation, it also led many US factories to relocate to Mexico to take advantage of lower wages, resulting in job losses in higher-paying US manufacturing jobs.
