Maritime issues are rising to the forefront of Asian security concerns. But
maritime management regimes can constrain conflict and create confidence i
n co-operation. Such regimes can define the range of permissible state beha
vior and resolve dilemmas stemming from the sharing of common resources. Re
gimes originate through imposition, spontaneous processes, or negotiation a
nd are supplied when there is sufficient demand for the functions they perf
orm. Integrative forces that support regime formation are the existence of
other international arrangements in the region; ethnic, cultural, or histor
ical interstate relationships; and clear indications of benefits to be gain
ed. Often a shock or crisis enhances regime formation or its robustness. Di
sintegrative forces include political or territorial differences, competiti
on for leadership, and opposition to regionalism. In regional co-operation
on maritime issues, Southeast Asia is clearly more advanced than Northeast
Asia. However, the absence of robust multilateral maritime regimes in Asia
reflects state perceptions that the costs outweigh the benefits. The primac
y of dis-integrative factors argues strongly for an ad hoc, issue-specific,
evolutionary process for multilateral maritime regime building in Asia.
