**Mexico Lifts Ban on Genetically Modified Corn from the United States**
In a recent development fulfilling the terms under the USMCA (United States-Mexico-Canada Agreement), the Mexican federal government has repealed its ban on importing genetically modified (GM) corn from the United States. This decision was officially published by the Secretaría de Economía in the Diario Oficial de la Federación on February 5, 2025.
The U.S. had initiated a dispute resolution panel under USMCA after Mexico’s 2023 decree by former President Andrés Manuel López Obrador, which aimed at substituting glyphosate in agriculture and banning GM corn for human consumption. On December 20, 2024, the panel ruled in favor of the U.S., stating that the Mexican measures lacked a scientific basis and unfairly restricted market access.
The Mexican Secretaría de Economía had been obliged to revoke prior restrictions and lift the ban as of February 2025, despite opposition in Mexico. President Claudia Sheinbaum had previously submitted a legislative proposal to the Mexican Congress aiming to enshrine the prohibition of GM corn cultivation in the constitution, emphasizing the cultural and ecological significance of native maize varieties to Mexico.
In response to the panel’s decision, the Mexican government, though not in agreement, has vowed respect for the ruling in the interests of maintaining treaty compliance. Nonetheless, the government intends to continue safeguarding public health, biodiversity, and indigenous rights, crucial components recognized by the panel.

**The Broader Implications of Lifting Mexico’s GM Corn Ban**
The repeal of the GM corn import ban in Mexico holds several implications, especially for trade dynamics and agricultural practices. Recently, the U.S. Secretary of Agriculture, Tom Vilsack, commented on the decision, highlighting the assurance it brings to American agricultural producers seeking access to Mexican markets. The resolution via the USMCA dispute mechanism underscored the importance of science-based policy formulation in international trade.
Moreover, this resolution is anticipated to reinforce trade relationships under the USMCA framework, which had previously seen tensions over biotechnology and agricultural practices. The ruling aligns with U.S. efforts to address climate change and enhance crop productivity through biotechnological innovations.
While cooperation on trade continues, the Mexican government may still pursue legislative avenues to support traditional agricultural practices. President Sheinbaum’s commitment to local biodiversity and agroecology reflects domestic pressures to protect the country’s extensive genetic resources in maize cultivation.
This ongoing tension between international treaties and national sovereignty in agricultural policymaking highlights the need for balance, ensuring that trade benefits do not overshadow environmental sustainability and cultural heritage.
