Mexico has modified its proposal to prohibit the import of genetically modified (GM) corn, specifically for animal feed, after receiving threat of retaliation from the United States. This modification does not impact Mexico's stance on banning GM corn for human consumption and the use of glyphosate. The USMCA free trade agreement is a focal point of controversy, as Mexico's proposed ban is perceived to violate its stipulations. Despite modifying its stance, the US continues to express concerns and maintains a science-based approach to agricultural trade.
