In the 2016 U.S. presidential election, Donald Trump`s campaign included a promise to renegotiate or eliminate NAFTA if the renegotiations fail.  After the election, Trump made a series of changes that influenced trade relations with other countries. The exit from the Paris Agreement, the cessation of participation in the Trans-Pacific Partnership negotiations and the significantly larger increase in tariffs with China were some of the steps he took, which reinforced the fact that he was serious about changing NAFTA.  Much of the debate about the virtues and errors of the USMCA resembles the debate on all free trade agreements (FTAs), such as the nature of free trade agreements as public goods, potential violations of national sovereignty and the role of commercial, labour, environmental and consumer interests in the development of the language of trade agreements. Democrats and Republicans appreciate the fact that the USMCA contains some of the most comprehensive environmental protection measures in a trade agreement in American history. Trump presents the agreement as a “new business model for the 21st century.” In a speech to supporters at a rally in New Jersey on Tuesday night, Trump said, “Tomorrow we will replace the NAFTA nightmare, one of the worst trade deals in history.” The agreement between the United States of America, the United States of Mexico and Canada, commonly known as the United States-Mexico-Canada Agreement (USMCA), is a free trade agreement between Canada, Mexico and the United States in lieu of the North American Free Trade Agreement (NAFTA).    The agreement has been referred to as NAFTA 2.0 or “New ALEFTA, since many nafta provisions have been introduced and its amendments have been found to be largely incremental. On 1 July 2020, the USMCA came into force in all Member States. On April 24, 2020, U.S.
Trade Representative Robert Lighthizer formally announced to Congress that the new trade agreement is expected to come into effect on July 1, 2020, and he also informed Canada and Mexico.  “We have a trade deficit with Mexico,” Toomey said. “All the credible and serious economists I know think it doesn`t matter to the extent of economic health. But that is not the administration`s point of view. I think they intend to renegotiate nafta to reduce trade with Mexico. NAFTA, which came into force in 1994, broke trade barriers between the three North American countries and trade between them increased.
