Afghanistan is often mentioned as a threat to the Central Asian states. Potential spillovers of violence, extremism, terrorism and dangers related to the drug trade are seen as significant security issues for the region. This article takes a different approach. Taking a performative view of statehood, we see state identities as socially constituted, partly by involvement in regional and global processes. From research on border management, the Northern Distribution Network, and various forms of bilateral cooperation between Afghanistan and the Central Asian states, we argue that Afghanistan has become an arena where the Central Asian states can participate. How the Central Asian states bordering on Afghanistan are treated as relevant participants, regardless of actual state capacity or the effectiveness of their policies, serves to constitute and confirm their sovereignty and relevance to the international community, and ultimately their statehood. By emphasizing the important state effects of their performance, our perspective differs from accounts of Central Asian states as either 'weak' or 'strong', and the tendency to depict Central Asian engagement in regional initiatives as mere window-dressing.
