Transgenic crops have been widely grown worldwide in recent years and a great deal of social, economic and environmental benefit has been achieved. The Chinese government has considered the recombinant DNA technology, closely combined with the conventional techniques, as a key factor for its sustainable agriculture development to ensure food security. In past decades, more and more investments were allocated to promote the R & D in this field. The philosophy bind this is that we should be aware of the most severe risk for a developing country like China, is sit idle and do nothing in developing own biotechnology. Meanwhile, for safe use of genetically modified organisms (GMOs) to ensure environment safety and human health, both government and private sector-funded research on safety of GM crops have been significantly increased during recent 5 years. For example, there are government-funded 4 projects in the National Transgenic Crop Program, 6 projects in the 863 National High-Tech Program, 7 projects in the 973 National Fundamental Science Program, and 3 projects in the National Key Program for Tenth Five-Year-Planning. Gene flow from transgenic crops is one of the major concerns regarding biosafety of GM crops. In this article the results obtained to date in China are reviewed.
