Please suggest a road map to establish strong regional organisation in Asia like different establishment under American Convention on Human Rights and European Convention on Human Rights.
I am not sure if I understand correctly your question. From a theoretical and Eurocentric point of view I would say that the economic interdependence increases through the introduction of a democratic political system. At the same time, higher interdependence requires more and better co-ordination. This leads finally to the creation of different institutions in
order to reduce the transaction costs. The European experience testifies that democracy encourages economic interdependence and the interdependence influence the creation of an institutional framework. On the other hand, institutions encourage the rise of interdependence. But it is assumed that economic interdependence must mature in order to reach the threshold level, and thus make the co-ordination indispensable. Once the institutional framework is established, institutions and exchange enter in mutual dependence. If this is right, it can be affirmed that regionalization promotes regionalism and once established the regionalism, both develop a mutual dynamic.
The idea of maturity of the interactions is not new as the works of K.W. Deutsch
(1954) and his colleagues (1957) show. They introduced the concept of security communities.
Inherent to the building of these communities is a communication process that leads to the formation of a common identification, a mutual identity and the creation of a kind of we-ness between the parts involved in the construction of such a community.
In sum, you need a more or less symmetric interdependence off all involved in the region. This interdependence must surpass the so-called threshold level. The threshold level could be define as that all the parts involved in the region perceive these interaction in such a way, that they really see the need to create an institution that helps to lower transaction costs. Have a look on the work of Karl W. Deutsch, really a very seminal work.
