China has a very strict rules on GMO products, but people still question the safety of GMO foods. According to the International Service for the Acquisition of Agri-biotech Applications, people around the world planted nearly 180 million hectares of biotech crops in 2015, up one hundred fold since 1996. So far, China only allows people to plant GMO cotton and papayas. But it does import a number of GMO products, including soybeans, a major source of cooking oil.
