The adoption of NAFTA led to the removal or removal of 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 benefited North American economies and average citizens, but has harmed a small minority of workers in sectors exposed to commercial competition.   Economists have estimated that an exit from NAFTA or a renegotiation of NAFTA in a way that would have restored trade barriers would have affected the U.S. economy and cost jobs.

On June 1, 2020, the USTR Robert Lighthizer office unblocked the Uniform Rules, the last hurdle before the agreement was implemented on July 1, 2020.

The leaders of Canada and Mexico have expressed their willingness to cooperate with the Trump administration.  Although he is vague about the exact terms he wants in a renegotiated NAFTA, Trump has threatened to withdraw from it if negotiations fail.
 According to Chad Bown of the Peterson Institute for International Economics, the Trump administration`s list is “very much in line with the attitude of the president, who likes trade barriers and loves protectionism. In 2009, the United States recorded a trade surplus of $28.3 billion with NAFTA countries for services and a trade deficit of $94.6 billion (annual increase of 36.4%) for goods in 2010. This trade deficit accounted for 26.8% of the total U.S. trade deficit.  A study on global trade, published in 2018 by the Center for International Relations, identified irregularities in the trade models of the NAFTA ecosystem using networked analysis techniques. The study showed that the US trade balance has been influenced by opportunities for tax evasion in Ireland.  Under the leadership of President Donald J. Trump renegotiated the North American Free Trade Agreement and replaced it with an updated and rebalanced agreement that works much better for North America, the Agreement between the United States, Mexico and Canada (USMCA), which went into effect on July 1, 2020. The USMCA is a beneficial asset for both parties for North American workers, farmers, ranchers and businesses. The agreement creates more balanced and reciprocal trade, which supports high-paying jobs for Americans and the North American economy is growing.. . .
