Abstract
The national Councils for Security Cooperation in the Asia-Pacific (CSCAPs) are fine exemplars of Track II security diplomacy whose mission is to prepare studies on security matters for their governmental Track I counterparts in the ASEAN Regional Forum (ARF). The CSCAPs also provide a test of propositions drawn from the epistemic community literature in inter-national relations which posits that non-governmental experts can influence government decision-making. This study of CSCAP activities and their impact on the ARF provides some support for epistemic community propositions. However, other findings suggest that epistemic community theory requires modification to take account of the blurred line between Tracks I and II in CSCAP. Nevertheless, the CSCAPs have achieved some noteworthy successes, including a definition of preventive diplomacy adopted by the ARF. On balance, then, Track II epistemic communities are playing a significant role in Track I security deliberations in the Asia-Pacific.
