Researcher Ana de Ita says Mexico's Senate approved the Law for the Promotion and Protection of Corn during the COVID-19 quarantine, when affected communities could not mobilize. She argues the law does not stop genetically modified corn and is a setback for native maize.
The law leaves open GM corn planting and commercialization in Mexico, the top export market for US corn, so near-term trade flows are not clearly affected. Any future restrictions on GM imports would matter more for US corn prices.
