In a clear message to Trump, economic leaders on Tuesday urged the three countries to oppose the imposition of tariffs „and other barriers or measures that will undermine the objectives of the comprehensive trade agreement and weaken North America`s competitiveness.“ CUSMA, as it is called Canada, but known as the USMCA in the United States, replaces the North American Free Trade Agreement (NAFTA) signed in 1994. At the time, it created the world`s largest free trade agreement. The U.S.-Mexico 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.  The Canada-Mexico-U.S. trade agreement will officially enter into force on July 1. It also establishes a list of cheese names that Mexico and the United States can agree to be marketed without restriction in their country, and it requires food stores in British Columbia to stop their practice, to sell only British Columbia wines on certain shelves and to store American wines next to them. On June 1, 2020, USTR Robert Lighthizer`s office released the uniform rules, which are the final hurdle before the agreement is implemented on July 1, 2020. The text of the agreement can be found here: ustr.gov/trade-agreements/free-trade-agreements/united-states-mexico-canada-agreement/uniform-regulations The formal negotiation process began on May 18, 2017, when the USTR announced to Congress that it wanted to renegotiate NAFTA starting at 90 days.  In accordance with the trade promotion authority`s statutes, the USTR published its document on the main objectives of the negotiations on 7 July 2017. Negotiations began on August 16, 2017 and continued until April 8, 2018.
Without a solution, Lighthizer said on May 2, 2018, that negotiations would be suspended until 2019 until 2019 if no agreement was reached at the end of the month. This statement was justified by the impending change of government in Mexico, during which the then President, Andres Manuel Lopez Obrador, did not agree with much of the negotiated language and was perhaps unwilling to sign the agreement. A new addition to the USMCA is the inclusion of Chapter 33, which covers macroeconomic policies and exchange rate issues. This is considered important because it could set a precedent for future trade agreements.  Chapter 33 sets out requirements for currency and macroeconomic transparency that, in the event of a breach, would be grounds for litigation under Chapter 20.  The United States, Canada and Mexico currently meet all of these transparency requirements in addition to substantive policy requirements that comply with the international Monetary Fund`s articles.  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, which succeeds 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.
