ABSTRACT
From the viewpoint of international law, we can speak about treaty regionalism represented by international treaties concluded among the states in concrete regions. The main impulse for regional regulation is the degree to which the involved states used it, connected with the need to regulate certain aspects of such use by international law. Regional treaties of this type obviously regulate a common legal regime of this geographical element as well as the rights and obligations of state parties. Institutional regionalism is traditionally represented through international intergovernmental organizations of regional character established predominantly on the basis of international treaties for the purposes of fulfilling the tasks within the agreed field. A legal regime that the member states of a regional organization created tends to be geographically determined by the state territories of its members because it is there that the organization is entitled to carry out its competencies.
