Advanced maritime countries such as U.S., Canada, Australia, have been initiated in integrated oceans management through enactment of oceans laws and establishment of ocean policies since UNCLOS and Agenda 21. However, the oceans policies of U.S., Canada and Australia show some limitations in view of integration because of its inherent characteristics of federal government systems. The U.S., Canada and Australia have not a leading agency for integrated oceans policies, have not included jurisdiction of local governments in federal government oceans policies, and have not addressed support to private oceans sector in their ocean policies. Instead, those countries have established ad-hoc oceans committee to achieve cooperation and coordination in oceans management.
