As former Assistant Secretary of State for East Asian and Pacific Affairs S
tanley Roth has observed, though overlooked by some and undervalued by othe
rs, multilateral cooperation has become an important and likely permanent f
eature of Asia's security landscape. In the decade following the end of the
Cold War, the scope of activities involved in the emerging network of mult
ilateral initiatives has widened dramatically, reflecting the general conse
nsus in the region of the need for cooperative frameworks that go beyond tr
aditional bilateral relations in addressing certain security concerns. Such
a growing pattern of what may be termed "security pluralism" is meant for
regional institutions and organizations to complement each other in develop
ing an informal security framework for promoting understanding and mutual c
onfidence. In the midst of strategic uncertainty and mistrust caused thy th
e growing rivalry between the US and China, compounded by the prospects of
prolonged instability on the Korean peninsula, multilateral security cooper
ation has a chance to perform a number of extremely useful functions. This
paper attempts to analyze what those functions are, while also evaluating v
arious approaches to regional security. In this process, several arguments
will be put forward to demonstrate the belief that a combination of endorsi
ng multi-layered security networks while strengthening bilateral alliances
provides the best formula for increasing regional security and stability in
Northeast Asia.
