Tourism is one of the leading sectors in the world economy. Enhancing its well-known economic, social and environmental benefits while managing its negative impacts are highly important for the national governments in European Union. Strategic planning is essential to meet the long term requirements of sustainability. National sustainable development strategies and tourism strategies are fundamental means of strategic planning as they provide guidance for the decision-makers of the tourism sector. The member states of the European Union have prepared their national sustainable development strategies, furthermore the Union’s common strategy and the national strategies of some member states have already been revised and renewed by now.The Hungarian strategies – National Sustainable Development Strategy and National Tourism Development Strategy – were completed the World Tourism Organization published its twelve aims for an agenda for sustainable tourism in 2005. Consequently these strategies are expected to contain references to the sustainability requirements and environmental, economic and socio-cultural aspects of tourism development. In the present study we analyse the issues of sustainable tourism development in the sustainable development strategies of the EU and Hungary and the National Tourism Development Strategy of Hungary 2005-2013 with special attention to the principles laid down by the WTO in 2005. Our aim is to investigate the cohesion between the principles of sustainable development and sustainable tourism, and their manifestations in some of the strategic documents influencing Hungarian tourism development.
