From the Overview: "On November 30, 2018, President Trump and the leaders of Canada and Mexico signed the United States-Mexico-Canada Agreement (USMCA). Concluded on September 30, 2018, USMCA would revise and modernize the North American Free Trade Agreement (NAFTA). Pursuant to trade promotion authority (TPA), the Administration notified Congress of its intention to enter into an agreement with Mexico, and with Canada if it was willing to join. On September 30, 2018, the United States Trade Representative (USTR) announced that the three countries had reached an agreement on a USMCA trade deal that would revise, modernize, and replace NAFTA upon ratification. On May 30, 2019, the Administration submitted a draft Statement of Administrative Action (SAA) to implement the proposed USMCA and a copy of the legal text, in accordance with TPA procedures. This product provides preliminary comparative analysis between the two agreements."
