From ambiguity to contestation: discourse(s) of non-traditional security in the ASEAN community

‘Non-traditional security’ (NTS) is prominently featured in the agenda of the Association of Southeast Asian Nations (ASEAN) and other ASEAN-led institutions in the Asia-Pacific. ‘NTS’ brings together a series transnational and non-military security threats that are considered common among regional states, urgent for them to attend to, and non-sensitive all at the same time. This a priori makes it a self-evident focus of attempts to bring regional security cooperation ‘to a higher plane’. However, this paper reveals that the uncontroversial character of NTS is overestimated, by shedding light on the co-existence of divergent – and potentially contradictory – interpretations of its meaning and implications in ASEAN and the wider region. In a context where ASEAN's relevance to the pursuit of regional security is increasingly being measured against its (in)ability to provide a coherent approach to security challenges that affect the region, the contested nature of NTS has important implications for the grouping's resilience in the twenty-first century.
