Tracing the debate on the importance and influence of the Shanghai Cooperation Organisation (SCO) on regional security integration in Central Asia, this work assesses the degree of its integration. It mainly addresses the interplay between individual state security needs, norms and identities. My proposed perspective is based on constructivism, informed by the English school. The paper concludes that security cooperation between SCO member states in the security environment is impacted by three factors: 1) security, influenced by 2) identities and norms, inducing states to utilise 3) the functions of organisation to their needs. The work explores the implications of such security cooperation in the context of perceptions and the conduct of cooperation research.
