The Nanjing Municipal Environmental Protection Bureau has detected that the "Xianyu 335" corn seeds sold on a large scale in China by the American company DuPont Pioneer as "hybrid corn" contain a "promoter" and are indeed genetically modified varieties. Therefore, the American company DuPont Pioneer has been suspected of "commercial fraud" in China. However, due to tremendous pressure from the U.S. company DuPont Pioneer’s “protective umbrella” in China, the Nanjing Municipal Environmental Protection Bureau was unwilling to publish the test results of “Xianyu 335”. However, the truth about the large-scale "illegal sales" of genetically modified corn seeds by the American company DuPont Pioneer in China cannot be concealed and will be exposed sooner or later. At present, the Ministry of Agriculture has quietly withdrawn its official recommendation of "Xianyu 335". The arrogant DuPont Pioneer Company of the United States and its "pseudo science popularization spokesperson" Fang Zhouzi did not make unreasonable excuses for "Xianyu 335" as a genetically modified variety like last year's "International Herald Tribune" first reported "The Mouse is Missing" "refuting rumors" and even "protesting" to the Ministry of Agriculture. These are "important signals" indicating that the American DuPont Pioneer Company and its "pseudo science popularization spokesperson" Fang Zhouzi, who illegally sold "Xianyu 335" on a large scale in China, have gone bankrupt. .Not long ago, the Ministry of Agriculture, the Ministry of Environmental Protection, the Ministry of Health, and the Ministry of Commerce organized a joint investigation team to Shanxi to investigate the truth about the ecological disaster caused by "Xianyu 335". Regardless of whether the conclusion is announced, it is a hasty denial by the Shanxi Provincial Department of Agriculture last year. Xianyu 335” is a genetically modified species and the disappearance of rats in Shanxi and Jilin is not a resounding slap in the face of genetically modified ecological disaster. In other words, the Shanxi Provincial Department of Agriculture and the Ministry of Agriculture, which recognized its absurd "rumor refuting", have also been credit-bankrupt.
