U.S. to challenge Mexico’s ban on geneticall­y modified corn

- By Ana Swanson and Linda Qiu

The Biden administra­tion said on Monday that it would take initial steps toward challengin­g a ban that Mexico has placed on shipments of geneticall­y modified corn from the United States, restrictio­ns that have rankled farmers and threatened a profitable export.

Mexico has planned to phase out the use of geneticall­y modified corn, as well as an herbicide called glyphosate, by 2024. About 90% of corn grown in the United States is geneticall­y modified.

Senior administra­tion officials have expressed concerns to the Mexican government about the measures for more than a year in virtual and in- person meetings, saying they could disrupt millions of dollars of agricultur­al trade and cause serious harm to U. S. producers. Mexico is the second-largest market for U. S. corn, after China.

On Monday, U. S. officials said that they were requesting consultati­ons over the issue with their Mexican counterpar­ts under the terms of the United States- Mexico- Canada Agreement, which governs the terms of trade in North America. Biden officials said that parties to that agreement, which was signed in 2020, had committed to base their regulation on science, and that Mexico’s ban on geneticall­y modified corn did not conform to those promises.

The consultati­ons are the first step in a process that could lead to the United States bringing a formal dispute against Mexico. The parties must meet to discuss the issue within 30 days and, if the talks are not successful, the United States could turn to a separate dispute settlement procedure under the trade agreement. That process that could potentiall­y result in the United States placing tariffs on Mexican products, if no other resolution can be reached.

Senior officials with the Office of the U. S. Trade Representa­tive said they were focused on finding a resolution through the talks at hand. But in a statement, the office said that it would “consider all options, including taking formal steps to enforce U. S. rights under the USMCA” if the issue was not resolved.

Mexico bought more than 20 million metric tons of corn from the United States in the 202122 marketing year, which runs from September to August, according to the U. S. Department of Agricultur­e.

The National Corn Growers Associatio­n has said that the impending ban would be “catastroph­ic” for American corn producers and Mexican consumers alike and undermine the principles of the trade agreement.

The industry has maintained that bioenginee­red corn is safe for human consumptio­n, contrary to health concerns cited by Mexican officials.

That view is widely shared by scientists, but consumers and Mexican officials remain wary of geneticall­y modified crops.

In the United States, the vast majority of corn planted has been bioenginee­red to be resistant to herbicides and insects. Bt- corn, for example, contains a gene from a soil bacterium that kills the European corn borer, an insect that feeds on maize and other grasses.

Corn can also be modified to be resistant to glyphosate, the most widely used herbicide in agricultur­e and lawn maintenanc­e in the United States. Glyphosate-based products like Roundup are sprayed on fields, killing weeds and leaving the resistant crops intact.
