According to Chad Bown of the Peterson Institute for International Economics, the Trump administration`s list „aligns very well with the president`s position of liking trade barriers and loving protectionism. In many ways, this makes NAFTA less of a free trade agreement.  The concerns expressed by the U.S. Trade Representative about subsidized state-owned enterprises and currency manipulation do not apply to Canada and Mexico, but are intended to send a message to countries outside North America.  Jeffrey Schott of the Peterson Institute for International Economics noted that it would not be possible to conclude the renegotiations quickly while addressing all the concerns on the list.  He also said that anything would be difficult to do to address trade deficits.  The objective of NAFTA was to remove barriers to trade and investment between the United States, Canada and Mexico. The introduction of NAFTA on 1. January 1994 saw the immediate removal of tariffs on more than half of Mexico`s exports to the United States and more than a third of U.S.
exports to Mexico. Within 10 years of the implementation of the agreement, all tariffs between the United States and Mexico should be eliminated, with the exception of certain U.S. agricultural exports to Mexico, which are expected to expire within 15 years.  Most of the trade between the United States and Canada was already duty-free. NAFTA also aimed to eliminate non-tariff barriers to trade and protect intellectual property rights in traded goods. The United States is a member of the World Trade Organization (WTO) and the Marrakesh Agreement Establishing the World Trade Organization (WTO Agreement) establishes rules for trade among the 154 WTO Members. The United States and other WTO members are currently participating in the Doha Round of Global Trade Negotiations for Development, and a strong and open Doha Agreement on markets for goods and services would be an important contribution to overcoming the global economic crisis and restoring the role of trade in economic growth and development. The United States has free trade agreements (FTAs) with 20 countries. These free trade agreements are based on the WTO Agreement and have broader and stricter disciplines than the WTO Agreement. Many of our free trade agreements are bilateral agreements between two governments. But some, such as the North American Free Trade Agreement and the Dominican Republic-Central America-United States Free Trade Agreement, are multilateral agreements between several parties. The previous free trade agreement between Canada and the United States had been controversial and divisive in Canada and had been treated as an issue in the 1988 Canadian election.
In this election, more Canadians voted for anti-free trade parties (the Liberals and the New Democrats), but the division of votes between the two parties meant that the pro-free trade Progressive Conservatives (P.C.) with the most seats emerged from the election and thus took power. Mulroney and the Progressive Conservatives had a parliamentary majority and easily passed the Canada-U.S. free trade and NAFTA laws in 1987. Mulroney, however, was replaced as Conservative leader and prime minister by Kim Campbell. Campbell led the Progressive Conservative Party until the 1993 election, when he was decimated by Jean Chrétien`s Liberal Party, which ran on a promise to renegotiate or repeal NAFTA. Chrétien then negotiated two additional agreements with Bush, who had undermined ALC`s consultation process, and worked to „accelerate“ the signing before the end of his term, which had run out of time and was expected to forward the necessary ratification and signature of the implementation law to the new President Bill Clinton.  According to the International Organization for Migration, the number of migrant deaths has increased worldwide with 5,604 deaths in 2016.  An increase in the number of undocumented agricultural workers in California could be due to the initial adoption of NAFTA.  Many U.S. small businesses relied on exporting their products to Canada or Mexico under NAFTA. According to the U.S. Trade Representative, this trade has supported more than 140,000 small and medium-sized businesses in the United States.
 According to a 2012 study, trade with the United States and Mexico increased by only a modest 11% with the reduction of NAFTA trade tariffs in Canada, compared to a 41% increase in the United States. and 118 per cent for Mexico. :3 In addition, the United States and Mexico benefited more from the tariff reduction component, with increases in social assistance of 0.08% and 1.31%, respectively, with Canada recording a decrease of 0.06%. :4 Beginning with the administration of Theodore Roosevelt, the United States became a major player in international trade, particularly with its neighboring territories in the Caribbean and Latin America. Today, the United States has become a leader in the free trade movement, supporting groups such as the General Agreement on Tariffs and Trade (later the World Trade Organization). [Citation needed] It was expected that a Chapter 19 panel would consider whether the Agency`s conclusion was supported by „substantial evidence“. This standard was based on considerable consideration for the national agency. Some of the most controversial trade disputes in recent years, such as the softwood dispute between the United States and Canada, have been negotiated before Chapter 19 panels. The NAFTA Implementing Decree and the various amendments to incorporate NAFTA into Mexican legislation were promulgated on December 14, 1993 and entered into force on January 1, 1994.
 Although President Donald Trump warned Canada on September 1 that he would exclude them from a new trade deal if Canada did not comply with his demands, it is not clear that the Trump administration has the power to do so without congressional approval. :34–6 According to Congressional Research Service (CRS) reports, one of which was released in 2017 and the other on July 26, 2018, it is likely that congressional approval of significant changes to NAFTA would have to be obtained from President Trump before the changes can be implemented. :34–6 Methanex Corporation, a Canadian company, filed a $970 million lawsuit against the United States […].
