Regional organisations are created by countries from a particular geographic region. They form groups to promote their national interest in a cooperative manner. They try to establish their independent identity. This process of regional level cooperation is also called regionalism.While geographic linkages are important, sometimes some functional issues become the basis of regional cooperation. These can be in areas like transport and communication, energy, health, etc.The process of regionalism usually begins with a political dialogue amongst the participants. Such a dialogue may lead to the creation of an organisation. Organisations like the European Union (EU), Association of South-East Asian Nations (ASEAN), or South Asian Association for Regional Cooperation (SAARC) are examples of such regional groupings.
