MEXICO CITY — From the hundreds of millions of tortillas consumed every year to the countless tons of corn-enriched feed that fattens livestock and poultry, corn is perhaps Mexico’s most important agricultural commodity, one at the center of its life and culture.
Now corn has taken on a new role — as a powerful lever for Mexican officials in the run-up to talks over Nafta, the North American Free Trade Agreement.
The reason: Much of the corn that Mexico consumes comes from the United States, making it America’s top agricultural export to its southern neighbor. And even though President Trump appears to be pulling back from his vows to completely overhaul Nafta, Mexico has taken his threats to heart and has begun flexing its own muscle.
The Mexican government is exploring buying its corn elsewhere — including Argentina or Brazil — as well as increasing domestic production. In a fit of political pique, a Mexican senator even submitted a bill to eliminate corn purchases from the United States within three years.
