Trade panel strikes down Mexico GMO corn ban
A trade dispute panel convened under the US-Mexico-Canada Agreement (USMCA) ruled that Mexico’s import restrictions on US genetically modified corn violates the accord. The conflict stems from a presidential decree published by Mexico in February 2023 instating an immediate ban on the use of genetically modified corn in dough and tortillas, and a gradual end to its use in animal feed and other products. The panel determined that the ban was not based on science, and contravened the market access required under the USMCA. However, advocacy groups such as Greenpeace are proponents of the corn decree and implored the US to respect Mexico’s sovereignty, arguing that market dominance of patented GMO varieties leads to the decline of indigenous strains and threatens food security.
