The passage of NAFTA has removed or removed barriers to trade and investment between the United States, Canada and Mexico. The impact of the agreement on issues such as employment, the environment and economic growth has been the subject of political controversy. Most economic analyses have shown that NAFTA has been beneficial to North American economies and the average citizen, but has been detrimental to a small minority of workers in sectors subject to trade competition.   Economists have estimated that the withdrawal from NAFTA or the renegotiation of NAFTA, in a way that would have created restored trade barriers, would have affected the U.S. economy and cost jobs.    However, Mexico would have been much more affected, both in the short term and in the long term, by the loss of jobs and the reduction of economic growth.  WASHINGTON – President Trump on Wednesday signed legislation implementing the U.S.-Mexico-Canada Agreement (USMCA), fulfilling a central campaign promise to renegotiate North American economic infrastructure. After U.S. President Donald Trump took office in January 2017, he tried to replace NAFTA with a new agreement and began negotiations with Canada and Mexico.
In September 2018, the United States, Mexico and Canada reached an agreement to replace NAFTA with the U.S.-Mexico-Canada Agreement (USMCA), and the three countries had ratified it until March 2020. Nafta remained in effect until the implementation of the USMCA.  In April 2020, Canada and Mexico informed the United States that they were ready to implement the agreement.  The USMCA came into force on July 1, 2020 and replaced NAFTA. He took office with an executive mandate to begin the PROCESS of withdrawing from NAFTA and signed it almost several times. But more moderate advisers and business contacts have always discouraged the president from abolishing the agreement. 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.
 The absence of a trade agreement would restore tariffs on trade between the United States and Canada, as well as the United States and Mexico. Fourth, the new agreement offers more protection to patents and trademarks. As a result, many of the intellectual property rights negotiated in the Trans-Pacific Partnership, which were abandoned by Trump, will be taken over. The president wasted little time in announcing the new North American trade agreement, calling it a “colossal victory” for farmers and workers at the plant and “the largest, fairest, fairest, most balanced and most modern trade agreement ever achieved.” Democrats in the House of Representatives approved the deal in December 2019. Some Republicans in the Senate wanted to abolish steel and aluminum tariffs for Canada and Mexico, so President Trump cancelled them. It was passed by the Senate on January 16, 2020.
