(13)Thematic programmes should provide distinctive added value and complement programmes of a geographic nature, which constitute the main framework for Community cooperation with third countries. Development cooperation implemented through thematic programmes should be subsidiary to the geographic programmes set out in this Regulation and in Regulation (EC) No 1638/2006 and to cooperation under the EDF. Thematic programmes encompass a specific area of activity of interest to a group of partner countries not determined by geography, or cooperation activities addressed to various regions or groups of partner countries, or an international operation that is not geographically specific. They also have an important role in developing Community policies externally and ensuring sectoral consistency and visibility.
