President Trump’s relentless crusade against the North American Free Trade Agreement (NAFTA) is already creating trouble for a community the White House has long purported to champion: U.S. farmers. exclusive report from Reuters published on Thursday indicates that Mexican buyers are following through on their threats to shift away from U.S. suppliers. According to data from Mexico’s Agrifood and Fishery Information Service (SIAP), purchasers in the country imported ten times more corn from Brazil in 2017 — 583,000 metric tonnes, a 970 percent increase from 2016 — all purchases made in the last four months of the year. That trend is on track to continue in 2018, with severe implications for the United States. Mexico is the top importer of U.S. corn and second biggest buyer of U.S. soybeans, making the country a crucial trade partner. But as negotiations over NAFTA have soured, Mexico has increasingly looked to South America instead.
