The aim of these considerations was to present the effect of regulations implemented by the World Trade Organisation on the form of agricultural policy in the European Union. The first part of this paper introduces the subject of agriculture in GATT and the WTO as well as changes in the agricultural policy of the EC connected with negotiations held at that time. The second part of the paper concerns negotiations on agriculture conducted within the Development Round of the WTO as well as potential changes to the EU agricultural policy after 2013. The Common Agricultural Policy occupies a special position in the European Union. Its role is not limited to the protection of the EU market against foreign competition, but also serves many functions connected with food safety, sustainable development, regional cohesion and other common goals of the EU. Further liberalisation of CAP requires from the European Commission the support for this idea by the member countries. The future agricultural policy of the EU has to combine many contradictory goals, including the prevention of a reduction in agricultural revenue, protection of the European model of agriculture as well as assurance of competitiveness for European agricultural produce on the world market, at the simultaneous maintenance of obligations resulting from negotiations conducted with the WTO.
