NAFTA provides that a country can withdraw from the agreement „six months after the written resignation of the other parties.“ It also provides that the agreement will remain in force for the other parties.91 The North American Free Trade Agreement (NAFTA); in Spanish: Tratado de Libre Comercio de América del Norte, TLCAN; In French: North American Free Trade Agreement, ALNA) was an agreement signed by Canada, Mexico and the United States, creating a trilateral trade bloc in North America. The agreement came into force on January 1, 1994 and replaced the 1988 Canada-U.S. Free Trade Agreement.  The NAFTA trading bloc was one of the largest trading blocs in the world, after the proceeds of the home. Several studies have shown that NAFTA has brought economic and social benefits to the Mexican economy as a whole, but that the benefits have not been distributed equitably across the country.62 A 2011 World Bank study showed that growth in post-NAFTA trade integration had a positive effect on boosting the productivity of Mexican plants.63 Most post-NANA studies on economic impact have shown that the net impact on the Mexican economy tends to be positive, but modest. While there have been periods of positive and negative economic growth in Mexico following the implementation of the agreement, it is difficult to accurately measure the importance of these economic changes attributed to NAFTA. A World Bank study that assessed some of the economic effects of NAFTA on Mexico concluded that NAFTA has helped Mexico move closer to the level of development in the United States and Canada. The study indicates that NAFTA has helped Mexican manufacturers adapt more quickly to technological innovations in the United States; probably had a positive effect on the number and quality of employment; Reducing macroeconomic volatility or sharp fluctuations in Mexico`s GDP growth rate; Increased synchronization of economic cycles in Mexico, the United States and Canada; 64 Canada is the second largest trading partner of the United States with $578.6 billion crossing the border in both directions in 2016, resulting in a trade deficit of $12.1 billion. The United States is the sole buyer of Canadian products and a supplier of imports to Canada. Canada`s share of its exports to the United States continued to increase in the 1980s, from 60.6% in 1980 to 70.7% in 1989, the first year of the free trade agreement. Canada`s share of total exports to the United States continued to increase, reaching 87.7% in 2002.
However, the relative importance of the value of trade between the United States and Canada has declined in recent years. Since 2002, this percentage has fallen to 76.4% in 2016. The U.S. share of Canada`s total imports, which peaked at 70.0% in 1983, continued to decline to 52.1% in 2015 (Figure 6). Canada is pleased to note that this is the top export destination for 35 U.S. states.77 NAFTA parties have not explicitly stated how NAFTA should be renegotiated or what changes they could make if the agreement is amended. The agreement is more than 20 years old and renegotiation can be an opportunity to address issues that are not currently dealt with in NAFTA. The following selective topics may be some areas of discussion. According to a 2013 Jeff Faux article published by the Economic Policy Institute, California, Texas, Michigan and other high-concentration manufacturing states were most affected by NAFTA job losses.  According to a 2011 article by EPI economist Robert Scott, the trade agreement has „lost or supplanted“ some 682,900 U.S. jobs.
 Recent studies have agreed with congressional Research Service reports that NAFTA has little influence on manufacturing employment and automation, accounting for 87% of manufacturing job losses.  Methanex Corporation, a Canadian group, filed a complaint amounting to
