On December 12, 2019, the Mexican Senate adopted the revised treaty by 107 votes to 1.  On April 3, 2020, Mexico announced its readiness to implement the agreement and joined Canada, although it requested that its auto industry have additional time to comply with the agreement.  The United States had already concluded a free trade agreement with Canada in 1988, but the addition of a less developed country such as Mexico was unprecedented. Opponents of NAFTA have taken up wage differences with Mexico, which had only 30 percent of U.S. per capita income. U.S. presidential candidate Ross Perot said in 1992 that trade liberalization would cause a « huge noise » of American jobs fleeing the border. Supporters such as Presidents Bush and Clinton responded that the agreement would create hundreds of thousands of new jobs a year, while Mexican President Carlos Salinas de Gortari saw it as a chance to modernize Mexico`s economy so that it « exports goods, not people. » MEXICO CITY/WASHINGTON (Reuters) – Senior officials in Canada, Mexico and the United States signed a review on Tuesday of a quarter-century-old trade pact aimed at improving the enforcement of workers` rights and keeping the price of biologic drugs low by removing the patent provision. The pact catalyzed Mexico`s transition from one of the world`s most protectionist economies to one of the most trade-friendly. Mexico had dismantled many of its trade barriers after joining the WTO`s 1986 General Agreement on Tariffs and Trade (GATT) in 1986, but it still had an average level of tariffs before NAFTA [PDF] of 10%. Growing objections within Member States to U.S.
trade policy and various aspects of the USMCA have had an impact on the signing and ratification process. Mexico said it would not sign the USMCA if tariffs on steel and aluminum were maintained.  Based on the results of the November 6, 2018 U.S. election, it has been speculated that the greater power of Democrats in the House of Representatives could jeopardize the passage of the USMCA agreement.   Bill Pascrell, a senior Democrat, argued for changes to the USMCA to pass Congress.  Republicans have opposed the USMCA provisions that impose labour rights on LGBTQ and pregnant workers.  Forty Republicans in Congress have asked Mr. Trump not to sign an agreement that includes « the unprecedented integration of sexual orientation and the language of gender identity. » As a result, Trump ultimately signed a revised version that required each nation only to « policies it deems appropriate to protect workers from discrimination in the workplace » and said the United States would not be required to introduce additional non-discrimination laws.  The Canadian government expressed concern about the changes that have occurred under the USMCA agreement.  The FDA was an important member of the U.S. team that negotiated the U.S.-Mexico-Canada (USMCA) agreement, which came into effect on July 1 of this year.
From the FDA`s perspective, the agreement adapts regulatory standards to public administration practices, improves the quality of products available to U.S. consumers and a level playing field for U.S. companies. That seemed to put him in conflict with Trump`s spokeswoman, Stephanie Grisham, who said the White House would « impose hard » to pass the transposition law before the end of the year.
