The kick-off of a North American free trade area began with U.S. President Ronald Reagan, who made the idea part of his campaign by announcing his candidacy for president in November 1979.  Canada and the United States signed the Canada-U.S. Free Trade Agreement in 1988, and shortly thereafter, Mexican President Carlos Salinas de Gortari decided to address U.S. President George H.W. Bush to propose a similar agreement to make foreign investment after the Latin American debt crisis.  When the two leaders began negotiations, the Canadian government of Prime Minister Brian Mulroney feared that the benefits that Canada had gained through the Canada-U.S. free trade agreement would be undermined by a bilateral agreement between the United States and Mexico, and asked to be associated with the U.S.-Mexico talks.  The U.S.-Mexico-Canada agreement is based on the North American Free Trade Agreement (NAFTA), which originally came into force on January 1, 1994. The agreement under consideration was the result of more than a year of negotiations including possible U.S. tariffs on Canada, in addition to the possibility of separate bilateral agreements.  Does this mean that Canada and the United States are the winners of NAFTA and that Mexico is its loser? Maybe, but if so, why did Trump campaign in June 2015 with “When do we beat Mexico at the border? They don`t care about us, about our stupidity.
And now they`re hitting us economically”? The USMCA is expected to have a very small impact on the economy.  An International Monetary Fund (IMF) discussion paper published at the end of March 2019 stated that the agreement would have a “negligible” impact on the general economy.   The IMF study predicted that the USMCA “would have a negative impact on trade in the automotive, textile and clothing sectors, while achieving modest welfare gains, mainly due to improved access to the goods market, with a negligible impact on real GDP.”  The IMF study concluded that the economic benefits of the USMCA would be greatly enhanced if Trump`s trade war ended (i.e., if the United States lowered tariffs on imports of steel and aluminum from Canada and Mexico and lowering retaliatory duties on imports from the United States)  While thousands of U.S. auto workers lost their jobs as a result of NAFTA , they could undoubtedly have lost poor performance without them.
