NAFTA has not eliminated regulatory requirements for companies wishing to act internationally, such as rules of origin and documentation obligations, that determine whether certain products can be traded under NAFTA. The free trade agreement also provides for administrative, civil and criminal sanctions for companies that violate the laws or customs procedures of the three countries. Methanex Corporation, a Canadian group, has filed a $970 million complaint against the United States. Methanex said a California ban on methyltert-butyl ether (MTBE), a substance that had found its way into many wells in the state, was hurting the company`s sale of methanol. The complaint was dismissed, and the company was ordered to pay $3 million in fees to the U.S. government, based on the following argument: “But as a matter of general international law, a non-discriminatory regulation for a public purpose that is adopted in accordance with due process and, with respect to inter alios, a foreign investor or investments are not considered dispossessed and compensable unless specific commitments have been made taken by the foreign government of the day to consider investments that the government would refrain from regulating.  In its May 24, 2017 report, the Congressional Research Service (CRS) wrote that the economic impact of NAFTA on the U.S. economy was modest. In a 2015 report, the Congressional Research Service summarized several studies as follows: “In reality, NAFTA did not cause the huge job losses that critics feared, nor the significant economic benefits predicted by supporters.
The overall net effect of NAFTA on the U.S. economy appears to have been relatively small, not least because trade with Canada and Mexico accounts for a small percentage of U.S. GDP. However, there have been adjustment costs for workers and businesses as the three countries have prepared for more open trade and investment between their economies. :2 Clinton signed it on December 8, 1993; The agreement came into force on 1 January 1994.   At the signing ceremony, Clinton paid tribute to four people for their efforts to reach the historic trade agreement: Vice President Al Gore, Council of Economic Advisers Chair Laura Tyson, National Economic Council Director Robert Rubin and Republican Congressman David Dreier.  Clinton also said, “NAFTA means jobs. U.S. jobs and well-paying American jobs.
If I didn`t believe it, I wouldn`t support this agreement.  NAFTA replaced the old Canada-U.S. free trade agreement. If the Trans-Pacific Partnership of Origin (TPP) were to enter into force, existing agreements, such as NAFTA, would be reduced to provisions that do not conflict with the TPP or require greater trade liberalization than the TPP.  However, only Canada and Mexico would have the prospect of becoming members of the TPP after U.S. President Donald Trump withdrew the United States from the agreement in January 2017. In May 2017, the remaining 11 members of the TPP, including Canada and Mexico, agreed to pursue a revised version of the trade agreement without U.S. participation.  Supporters of NAFTA in the United States stressed that the pact was a free trade agreement and not an agreement on the Economic Community.  The free movement of goods, services and capital did not extend to work.
