Building upon the centuries-old business relationship between Mexico and the United States, NAFTA allowed both countries to benefit from a seamless workshop that clearly made the pie larger. The 25-year-old contract needed to be revised, though, with motor vehicles and auto parts taking the lion's share of the modifications (for better or worse depending on how well your company coordinates upstream and downstream operations and record-keeping).
Mexico's economic relevance to the United States is frequently overlooked. The 11th largest economy in the world, Mexico has a population (126 million) roughly 40 percent that of the U.S. and is close to three times the size of Texas. The country has a network of 12 Free Trade Agreements (FTAs) with 46 countries, and seven additional ones will be added with the renewed Trans-Pacific Partnership (an agreement now known as CPTT, Comprehensive and Progressive Agreement for Trans-Pacific Partnership, TPP 11 in short), from which the U.S. withdrew under the Trump Administration.
Mexico was, in 2018, either the first or second largest export market for more than 50 percent of states in the Union. (It was first for six states –Arizona, California, Kansas, Nebraska, New Mexico and Texas, and second for 22 States–Colorado, Georgia, Illinois, Indiana, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Dakota, Tennessee, and Wisconsin.) It is also the third-largest source of imports in the U.S.; has an expanding middle class that has grown accustomed to purchasing American goods and services; has demonstrated to be a near-shore, reliable manufacturing partner; as well as will benefit from a demographic bonus during the next several years that will help neutralize the dwindling U.S. population (and necessarily its workforce).
