Regardless of this, on May 11, 2018, House of Representatives spokesman Paul Ryan set May 17 as the deadline for congressional action. This deadline was not met and the agreement with Mexico was only concluded on 27 August 2018.  At that time, Canada had not yet approved the submitted agreement. Given that the outgoing President of Mexico, Enrique Peña Nieto, left office on 1 December 2018 and that 60 days of revision are required, the deadline for the submission of the agreed text was 30 September 2018, which was reached precisely on 30 September. Negotiators worked 24 hours a day and reached agreement on a draft text less than an hour before midnight on that date. The following day, October 1, 2018, the USMCA text was released as an agreed document. In addition to the provisions of the original NAFTA, the USMCA draws heavily on the Trans-Pacific Partnership (TPP) and Comprehensive and Progressive Trans-Pacific Partnership (CPTPP) trade agreements. On April 3, 2020, Mexico announced its readiness to implement the agreement and join Canada.  The agreement entered into force on 1 July 2020.
    Nafta contains three main dispute settlement mechanisms. Chapter 20 is the resolution mechanism from one country to another. It is often considered the least controversial of the three mechanisms and was maintained in the USMCA in its original NAFTA form. Such cases would involve complaints between USMCA member states for violation of a provision of the agreement.  Chapter 19 deals with the justification of anti-dumping or countervailing duties. Without Chapter 19, the remedy for the management of these policies would be through the national legal system. The two nations agreed on a historic agreement that put Canada and the United States at the forefront of trade liberalization.

The agreement provides for the disclosure of market interventions.
The IMF may be convened as an arbitrator in the event of a dispute between the parties.  The Trump administration`s Office of the U.S. Trade Representative proposed the USMCA citing new digital trade measures, stronger trade secret protection, and adaptations to rules of origin for motor vehicles as some of the benefits of the trade deal.  On June 1, 2020, the USTR office issued the Uniform Rules, which is the last hurdle before the agreement is implemented on July 1, 2020. . .
