Many workers and union leaders blame trade agreements such as NAFTA for declining employment in U.S. production. The U.S. auto sector has lost about 350,000 jobs – one-third of the industry – since 1994, while employment in Mexico`s auto sector has grown from 120,000 to 550,000. Things that have not been corrected, the agreement still has the limits to buy America, to buy local, to buy green politics. Why does a trade agreement bind Congress or national parliaments to public procurement? The uniform rules contain additional details on the rules of origin and origin of the agreement. | Canada | Mexico The agreement is the result of a renegotiation between the member states of the North American Free Trade Agreement, which informally approved the terms of the new agreement on 30 September 2018 and officially on 1 October.  The USMCA was proposed by U.S. President Donald Trump and signed on November 30, 2018 by Trump, Mexican President Enrique Pea Nieto and Canadian Prime Minister Justin Trudeau as a secondary event of the 2018 G20 summit in Buenos Aires.
A revised version was signed on December 10, 2019 and ratified by the three countries, with final ratification (Canada) taking place on March 13, 2020 just before the Canadian Parliament adjourned due to the COVID-19 pandemic. To facilitate the strengthening of cross-border trade, the United States has reached an agreement with Mexico and Canada to increase the value of de minimis delivery. For the first time in decades, Canada will increase its de minimis level from $20 ($15.38) to $40 ($30.77) for taxes. Canada will also offer duty-free shipments of up to 150 $US ($115.38). Mexico will continue to provide $50 de minimis exemptions and will also offer duty-free shipments of up to $117. Shipping rates to this level would be achieved with minimum formal entry procedures, which would allow more businesses, particularly small and medium-sized enterprises, to be part of cross-border trade. Canada will also allow the importer to pay taxes 90 days after the importer enters. An April 2019 Analysis by the International Trade Commission on the likely effects of the USMCA estimated that the agreement would increase U.S. real GDP by 0.35 percent if the agreement were fully implemented (six years after ratification) and would increase total U.S. employment by 0.12% (176,000 jobs).   The analysis cited by another Congressional Research Service study showed that the agreement would not have a measurable effect on employment, wages or overall economic growth.  In the summer of 2019, Larry Kudlow, Trump`s chief economic adviser (the director of the National Economic Council at Trump White House), made unfounded statements about the likely economic impact of the agreement and overstated forecasts related to jobs and GDP growth.
 A new addition to the USMCA is the inclusion of Chapter 33, which covers macroeconomic policies and exchange rate issues.
