ABSTRACT
This chapter focuses on the diplomatic aspects of the operation and development of regional organisations since 2000. It deals with a comparison with earlier regionalism developing after 1945, in order to provide context and setting. The chapter examines key aspects of the development of regional organisations since 2000, including membership, expansion of Regional organisation (RO) agendas, the role of external powers vis-a-vis regional organisations and the use of regions and regional actors as instruments in cultural diplomacy. RO interests intersect with the collective international agenda at various points through formal structures, consultation, debate, and responses to particular events or crises. The growing international recognition of the need for improved international governance mechanisms to enhance international cooperation combating transnational crime led to the creation in 1997 of the United Nations Office on Drugs and Crime. External actors have had a diverse often negative impact on the development of RO.
