The issue is Mexico's decision to ban the use of biotechnology corn in tortillas and dough.

The Mexican president has said the intention is to gradually substitute the use of biotechnology corn in all products for human consumption and animal feed, and the rejection of applications for authorizations covering the importation and sale of certain biotechnology products.

The United States has requested dispute settlement consultations with Mexico under the Canada-United States-Mexico Agreement (CUSMA).

Federal Agriculture Minister Marie-Claude Bibeau and the Minister of International Trade Mary Ng say Canada will participate as a third party in the dispute noting they share U.S concerns that Mexico’s measures are not scientifically supported and have the potential to unnecessarily disrupt trade in the North American market.
