The Mexican government, led by Claudia Sheinbaum, is taking steps to protect the native corn of Mexico from transgenic corn by refusing its entry, despite opposition from the United States and Canada as part of their free trade agreement. This decision is significant as Mexico's corn originated in Mexico over 10,000 years ago and holds a deep cultural meaning for the Mexican people. The government is willing to face trade repercussions, including potential tariffs or compensatory quotas on Mexican products, to uphold this cultural heritage and biodiversity. However, trade experts suggest that Mexico may need to consider revising its decrees banning genetically modified corn or engage in negotiations with its trade partners to prevent negative trade impacts.
