Indian intelligence agencies assess that Rohingya networks operate a self-financing model linking illegal migration, drug trafficking, and militancy. The methamphetamine trade, primarily originating from Myanmar and trans-shipped through Cox's Bazar, is identified as the main financial backbone, with an estimated regional trade value of billions annually. Portions of drug revenue are reportedly diverted to fund militant activities, with human trafficking routes deliberately intermixing migrants and drug couriers to evade detection. Traffickers charge significant fees for entry into India, with some payments allegedly siphoned to militant handlers.
