In addition, there is a provision that the agreement itself must be reviewed every six years by the three nations, with a 16-year forfeiture clause. The contract may be renewed for a period of 16 years during the six-year review period.  The introduction of the Sunset clause gives more control in the organization of the future of the USMCA in the hands of national governments. However, there is concern that this could lead to greater uncertainty. Sectors such as automotive require significant investment in cross-border supply chains.  Given the dominant position of the U.S. consumer market, it is likely that this will put pressure on companies to establish more production in the United States, with a higher probability of higher production costs for these vehicles.  The Trump administration`s office proposed the USMCA citing new digital trade measures, strengthening the protection of trade secrets and adapting the rules of origin of the automobile among the benefits of the trade agreement.  The agreement between the United States of America, the United States of Mexico and Canada is a free trade agreement between Canada, Mexico and the United States in lieu of 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.
The agreement is the result of a renegotiation between the member states of the North American Free Trade Agreement, which gave informal agreement on 30 September 2018 and officially on 1 October under the new agreement.  The USMCA was proposed by U.S. President Donald Trump and signed on November 30, 2018 by Trump, Mexican President Enrique Pea Nieto and Canadian Prime Minister Justin Trudeau as a secondary event of the 2018 G20 summit in Buenos Aires. A revised version was signed on December 10, 2019 and ratified by the three countries, with final ratification (Canada) taking place on March 13, 2020 just before the Canadian Parliament adjourned due to the COVID-19 pandemic.
