This study employs a neoclassical realist framework to explain the proliferation of industrial-scale scam compounds across mainland Southeast Asia. Addressing the puzzle of why divergent political systems, such as authoritarian personalism in Cambodia, one-party communist rule in Laos, and fragmented junta control in Myanmar, yield identical criminal ecosystems, this paper argues that these "grey enclaves" are not merely the result of weak governance. Rather, they are the unintended outcome of systemic economic pressures, specifically the Belt and Road Initiative (BRI), mediated by a distinct regional strategic culture. We posit that shared elite beliefs regarding stability, developmental pragmatism, and executive discretion create a permissive environment for institutional isomorphism.
Within this convergent field, transnational networks do not simply exploit corruption; they engage in cyber fraud, specifically leveraging AI-driven crime and cryptocrime. These adaptive groups engage in structural arbitrage, actively mimicking state bureaucratic forms and developmental rhetoric to embed themselves in the local political economy. By tracing the evolution of these networks into quasi-sovereign entities overseeing mass-scale cryptocurrency fraud and severe human rights abuses, this article demonstrates how criminal actors weaponise institutional convergence. Finally, this paper provides a translational policy critique, arguing that because these illicit ecosystems are deeply embedded in host-state developmental models, traditional law enforcement capacity-building fails, presenting a fundamentally new strategic and operational challenge for Australian and regional security.
