Security regimes constitute an important test of the 'liberal' school
of thought in contemporary international relations. In the Asia-Pacifi
c, interest is growing over how they may contribute to that region's f
uture order and stability. IT is argued here, however, that Asia-Pacif
ic security regimes cannot succeed unless 'realist' power-balancing st
rategies are first applied, affording time for patterns of structural
leadership to shape enduring security norms and institutions. The ASEA
N Regional Forum (ARF) is arguably the region's first potential post-c
old war security regime. Its fate, or that of its successor security r
egimes in the Asia-Pacific, depends upon satisfying four critical cond
itions for regime building and upon winning the acceptance of China an
d the United States, the region's two key 'structural leaders'. while
the ARF does not at present seem close to satisfying these criteria, i
t may help to provide the breathing space necessary for a successful t
ransition from a competitive cold war environment to a more cooperativ
e climate in the Asia-Pacific.
