There are different organic standards throughout the world. For example the USDA organic cert is relatively lax compared to that of the EU. China has one or two different organic certification agencies and a number of “green” standards. The green certificates started off as a means of helping farms who are not quite prepared with the set of management routines for organic certifications but are basically practicing organic practices. However, like almost anything with a good helping intention in China, they are quickly abused by corrupted officials for allies of not-so-environmental practices. Incidents of chemicals malpractices in farms or food factories with green certs or organic certs continue to happen every now and then.
Like Leo said, China is a huge country with the largest population. Everyone is watching it. A normal percent of criminals can be so easily noticeable. Even though the rate of corruption is high by any standards, chemical abuse incidents happen mostly inland, much less in things that are for export.
