During the election campaign, President Donald Trump promised to repeal NAFTA and other trade agreements that he considered unfair to the United States. On August 27, 2018, he announced a new trade agreement with Mexico to replace him. The U.S.-Mexico trade agreement, as it has been called, would maintain duty-free access for agricultural products on both sides of the border and eliminate non-tariff barriers, while encouraging more agricultural trade between Mexico and the United States and effectively replacing NAFTA. The debate on the impact of NAFTA on signatory countries continues. The agreement, which eliminated the largest number of tariffs on trade between the three countries, entered into force on 1 January 1994. .
