The international government of Central Asian Borders (Kyrgyzstan, Tajikistan, Uzbekistan, Kazakhstan, Turkmenistan) refers to projects in the field of border management that have been implemented by the OSCE, the European Commission, the UNODC and IOM between 1992 and 2012. These activities import and export a type of expertise aimed at bringing state boundaries in line with an imperative of mobility and security. But how does this border knowledge circulate across borders in the first place? During their life cycle, projects go through three different social universes. Firstly, they connect with Central Asian societies where control and flows intersect. They provide some equipment which only frames checks and controls to some extent. The steering committees deciding over these investments are embedded in a particular social universe that we call the field of operation. This second space is configured according to a capital whose volume corresponds to the level of autonomy that each implementing agency holds, and whose structure refers to their specialization in development and/or security. The practical logic of this field positively sanctions the accumulation of social capital by individual brokers. The authorization-giving arenas, finally, are situated in a transnational space polarized around Brussels and Vienna. Whilst Central Asia is constructed as a place of secondary interest within the field of Eurocracy, actors working from Vienna perceive this region as a more important issue. Subaltern transnational elites tend establish themselves in such unattractive areas because they gain leeway where they can re-establish themselves as important players from there.
