Analysis of International Coexistence Management of Genetically Modified and Non-Genetically Modified Crops

The coexistence of genetically modified (GM) and non-GM crops has been a subject of considerable concern, particularly in the context of the extensive utilisation of GM crops. In response to this concern, various countries have devised coexistence strategies that are tailored to their respective national contexts, taking into account economic, political, technological and public acceptability factors. In the context of planting, countries such as the United States and Brazil have adopted a strategy of coexistence management, whereby the responsibility for implementing isolation measures falls upon premium producers. In contrast, the European Union, Japan and other countries that import GM crops have enacted legislation requiring growers to adhere to stringent isolation measures to prevent the mixing of GM and non-GM crops. Internationally, GM products are distinguished by a labelling management system to satisfy the public's right to know and choose and to realise the coexistence of GM and non-GM during circulation and consumption. When considered in the context of China's specific national conditions, particularly the prevalence of a small-scale peasant economy, it is recommended that China draw upon the lessons learned from the field coexistence strategies employed in countries that have adopted GM planting. This recommendation involves the refinement and enhancement of existing labelling management practices as well as the formulation of a coexistence management policy that is characterised by cost savings, efficiency gains and robust operational capabilities. The implementation of these measures is expected to foster the commercialisation of GM soybean and maize in China.
