This paper seeks to find possibilities forreconciliation of the implementation of theprecautionary principle and the promotion ofinternational trade of genetically modified organisms,based on the assumption that a sustainabledevelopment is a right objective to strive for. Itstarts with an explanation of the background and therole of the precautionary principle, and describes inwhat way measures based on the precautionary principlecan easily lead to the creation of trade barriers. Thearticle then examines to what extent the WTO (WorldTrade Organisation) Agreements allow theimplementation of the (...) precautionary principle. Inaddition, structural conflicts between the perceptionof the precautionary principle and the concept oftrade liberalisation will be evoked. The last sectionof the paper analyses to what extent the WTO rulesprovide possibilities to avoid or solve theseconflicts in order to attempt to answer the mainquestion: are the precautionary principle and theinternational trade of genetically modified organismsreconcilable?
