(2) Chuin-Wei YAP, China Imports Argentina's GMO Corn. Dow Jones Newswires, Aug 7, 2013 http://www.agriculture.com/marke ... as-gmo-cn_9-ar32830
("Argentina is the world's second-largest corn exporter after the U.S.--sometimes its third-largest depending on Brazil's output * * * China's corn imports last year reached 5.2 million tons, of which the U.S. accounted for 98% and Argentina for 50 tons")
My comment: Of course, most corn produced in US is genetically modified. Presumably when China imported US corn in the past, China did not mention it was GMO, either.
