CHICAGO/WASHINGTON, March 6 (Reuters) - The United States has requested formal trade consultations with Mexico over U.S. objections to its southern neighbor's plans to limit imports of genetically modified corn and other agricultural biotechnology products. "We hope these consultations will be productive as we continue to work with Mexico to address these issues." The United States has previously threatened to take the issue to a trade dispute panel under the trilateral agreement with Mexico and Canada over the plan, which would ban genetically modified corn for human consumption. A USTR official said the talks would cover Mexico's planned rejection of GMO corn and other agricultural biotechnology products that have been shown to be safe in the United States and other countries for decades. Corn for food use comprises about 21% of Mexican corn imports from the U.S., a representative from the National Corn Growers Association said, citing U.S. Grains Council data.
