Title: History of Mexico
Content:   On 1 January 1994, Mexico became a full member of the North American Free Trade Agreement (NAFTA), joining the United States and Canada. Mexico has a free market economy that recently entered the trillion-dollar class. It contains a mixture of modern and outmoded industry and agriculture, increasingly dominated by the private sector. Recent administrations have expanded competition in sea ports, railroads, telecommunications, electricity generation, natural gas distribution, and airports. Per capita income is one-quarter that of the United States; income distribution remains highly unequal. Trade with the United States and Canada has tripled since the implementation of NAFTA. Mexico has free-trade agreements with more than 40 countries, governing 90% of its foreign commerce.
Title: Carlos Salinas de Gortari
Content:   The centerpiece of Salinas's presidency was his successful negotiation with the U.S. and Canada to create the North American Free Trade Agreement (NAFTA), which came into effect on 1 January 1994. The agreement was a reversal of Mexico's longstanding policies of economic nationalism and anti-Americanism and was intended to create a single market. Mexican proponents of NAFTA saw it in a way to secure markets for its exports and attract foreign investment, and create jobs, help the government to be able to service its foreign debt, and overall, promote economic recovery. In Mexico, the reversal was controversial, opposed by organized labor, many academics, and nongovernmental organizations.
Title: North American Free Trade Agreement
Content:  The goal of NAFTA was to eliminate barriers to trade and investment between the U.S., Canada and Mexico. The implementation of NAFTA on January 1, 1994, brought the immediate elimination of tariffs on more than one-half of Mexico's exports to the U.S. and more than one-third of U.S. exports to Mexico. Within 10 years of the implementation of the agreement, all U.S.–Mexico tariffs were to be eliminated except for some U.S. agricultural exports to Mexico, to be phased out within 15 years. Most U.S.–Canada trade was already duty-free. NAFTA also sought to eliminate non-tariff trade barriers and to protect the intellectual property rights on traded products. Chapter 20 provided a procedure for the international resolution of disputes over the application and interpretation of NAFTA. It was modeled after Chapter 69 of the Canada–United States Free Trade Agreement. NAFTA is, in part, implemented by Technical Working Groups composed of government officials from each of the three partner nations.

Title: United States–Mexico–Canada Agreement
Content:  The Agreement between the United States of America, the United Mexican States, and Canada, commonly known as the United States–Mexico–Canada Agreement (USMCA) in the United States and the Canada–United States–Mexico Agreement (CUSMA) in Canada, is a free trade agreement between Canada, Mexico, and the United States. It replaced the North American Free Trade Agreement (NAFTA) implemented in 1994, and is sometimes characterized as "NAFTA 2.0",   or "New NAFTA",  since it largely maintains or updates many provisions from its predecessor. USMCA resulted from renegotiations between the NAFTA member states beginning in 2017; characterized as "tumultuous", these centered primarily on "auto exports, steel and aluminum tariffs, and the dairy, egg, and poultry markets". All sides came to an informal agreement on September 30, 2018, which was formalized the following October 1.
