One of the main constraints to development in North East India is the lack of connectivity. How the existing East–West Corridor and the proposed transboundary corridors such as the Trilateral Highway, the Kaladan Multimodal Transit Transport Project, and the Bangladesh–China–India–Myanmar Economic Corridor connecting India with neighbouring countries in the eastern neighbourhood would stimulate economic activities in the North East is examined. It is found that the corridor-based development projects may generate economic activities and regional development, which, in turn, would influence economic growth through higher production and consumption.
