Following decades of disputes and failed negotiations, the maritime boundary between Bangladesh and India was finally established when the Permanent Court of Arbitration delivered its Award on 7 July 2014. The Tribunal first determined the location of the land boundary terminus, which served as the starting point of the maritime boundary, based on the terms of the 1947 Radcliffe Award. The Tribunal then established the boundary within the territorial sea using the equidistance methodology. Soon after exiting the territorial sea, the boundary was shifted slightly to the south, to follow a directional azimuth of N 177° 30′ E, until intersecting with the Bangladesh–Myanmar maritime boundary on the outer continental shelf.

Bangladesh and India also share a land boundary.
