A trade-dispute panel has ruled that Mexico’s export restrictions on genetically modified (GM) corn from the United States violate the US-Mexico-Canada Agreement (USMCA). This ruling underscores ongoing tensions between the two countries regarding biotechnology and agricultural trade regulations. The panel found that Mexico’s restrictions were not grounded in scientific evidence and thus conflicted with the market access stipulations under the USMCA. The decision, as outlined in a final report, has been welcomed by U.S. trade representatives who argue that such restrictions hinder trade growth in North America.
The dispute originated from a Mexican decree introduced in 2023, which instituted an immediate prohibition on the use of genetically engineered corn in traditional products like dough and tortillas. The decree also outlined a gradual phase-out of GM corn in animal feed and other goods. Mexico justified this decree by claiming it was necessary to protect public health and ensure a healthy environment through food quality and nutritional standards, as noted in the stated purpose of the decree.
US Trade Representative Katherine Tai announced the United States’ successful challenge against these restrictions, reiterating that the panel’s decision supports science-based, rules-driven trade as essential to USMCA agreements. Ambassador Doug McKalip also emphasized that the ruling fortifies U.S. positions on maintaining impartial, rule-based trade relations.
Despite this victory, advocacy groups in Mexico remain firm supporters of the corn decree, urging the United States to respect Mexico’s sovereignty and domestic policy choices. These groups argue that the restrictions are justified in their aim to preserve biodiversity and prevent potential health risks associated with genetically modified organisms. However, others maintain that the US is entitled to contest these restrictions under the trade agreement provisions, as they pose barriers to open trade between the two nations.
