The trade dispute over Mexico’s restrictions on genetically engineered (GE) corn and glyphosate, a pesticide that GE corn is designed to resist, recently entered a new phase. The dispute is turning from the governments’ submissions and rebuttals to a dialogue with the panelists who will ultimately decide the case. One issue up for debate is whether the Mexican government can assert its rights to honor commitments to Indigenous people and protect the environment and biodiversity under the terms of the U.S.-Mexico-Canada Agreement (USMCA).
Public hearings were held in Mexico City on June 26-27 and broadcast online. Much of the discussion focused on the process. The U.S. asserted that Mexico had failed to conduct a risk assessment carried out according to international standards. Mexico countered that its plans to gradually phase out imports of GE corn are still aspirational, one element of the bigger plans to increase self-sufficiency of corn and other basic foods that began under President Andrés Manuel López Obrador’s administration and will continue under the incoming administration of President-elect Claudia Sheinbaum. According to Mexican officials, when and if they consider restrictions on GE imports, Mexico will conduct a full risk assessment of GE corn in Mexico’s specific situation (where corn is a central part of the diet) and invite the U.S. to participate. In the meantime, they explained, the end use restrictions on white corn for human consumption don’t restrict imports, as white corn continues to be imported for other uses such as animal feed. In fact, both yellow and white corn exports to Mexico have increased substantially over the last few years.
The trade dispute is about both the scientific studies cited in risk assessments and the process for determining restrictions on imports. The whole idea behind a trade agreement, or really any international agreement, is that decisions are based on a set of rules. There is little doubt that the USMCA set in place rules that explicitly favor the free flow of goods and services and exacerbate corporate power. It’s also clear that we should choose entirely different rules, but in the meantime, this agreement formally establishes that governments have legitimate reasons to take actions to protect their peoples and environments, even when those actions affect trade. The text and context of the agreements matter.
