Governing the Gray Border: Physical Porosity, Smuggling Networks and Community Complicity along the Malaysia-Thailand Frontier

This article examines the Malaysia-Thailand border as a gray border space where state control, informal mobility, livelihood practices and illicit networks intersect. Moving beyond conventional understandings of borders as fixed territorial lines, it argues that border insecurity is produced through the interaction of physical porosity, economic incentives, community complicity and fragmented multi-agency enforcement. Drawing on qualitative fieldwork conducted between January and April 2026 in the Kubang Pasu border area of Kedah, the study examines how a configuration of eighteen enforcement agencies and roughly 1,550 personnel coexist with persistent informal mobility and contraband flows along a 45-kilometer frontier. The central finding is that unfenced terrain, breached fences, and informal crossings are reproduced not despite institutional density but partly through it, as overlapping mandates and uneven intelligence flows hollow out operational coherence. The article concludes that the governance problem at this frontier is one of incentive alignment across agencies rather than of enforcement capacity.
