The US has won a dispute panel under the USMCA against Mexico over the country's measures related to genetically modified (GM) corn. The panel found that Mexico's measures are not science-based and limit market access. Mexico has banned the use of GM corn seeds due to concerns about toxins and biodiversity risk, a move the US argues is not backed by science. Current Mexican administration plans to include a clause in the constitution to ban GM corn, while also ensuring self-sufficiency and biodiversity conservation of white corn. The administration also highlighted the dependence of farmers on seeds and the potential risks of genetically modified organisms.
