Sovereign Connectivity Statecraft: Kazakhstan’s Middle-Power Diplomacy and Central Asian Agency in a Fragmenting Eurasia

This article develops the concept of sovereign connectivity statecraft to explain how Kazakhstan seeks to convert geography, multi-vector diplomacy, transport corridors, resource endowment, institutional credibility, and regional public-good provision into autonomous bargaining capacity in a fragmented Eurasian order. The study is a conceptual review supported by qualitative document analysis of peer-reviewed scholarship, Kazakhstani policy documents, institutional reports, and recent trade, corridor, and resource data. It argues that multi-vector diplomacy remains necessary but insufficient: it describes Kazakhstan’s diversified external relations, whereas sovereign connectivity statecraft identifies the mechanism through which those relations are translated into usable routes, rules, partnerships, and regional services. The analysis specifies five mutually reinforcing pillars: sovereignty, balance, connectivity, institutional resilience, and regional public goods. Applied to the Middle Corridor, uranium and critical-mineral diplomacy, energy diversification, and regional consultation, the framework shows that Kazakhstan’s agency grows only when connective assets are matched by logistical reliability, domestic upgrading, transparent governance, and respect for neighboring states’ autonomy. The contribution is conceptual and empirical: it separates connectivity-based agency from hedging, geoeconomics, and ordinary multi-vectorism while grounding each pillar in traceable public indicators. The article concludes that Kazakhstan has acquired conditional platform-state functions, but these remain vulnerable to corridor bottlenecks, commodity concentration, implementation gaps, and geopolitical asymmetry.
