 The dispute over the Ambalat stretch of the Celebes Sea began with the publication of a map produced by Malaysia in 1979 showing its territorial waters and continental shelf.The map drew Malaysia's maritime boundary running in a southeast direction in the Celebes Sea from the eastmost point of the Indonesia-Malaysia land border on the eastern shore of Sebatik island, thus including the Ambalat blocks, or at least a large portion of it, within Malaysian territorial waters.Indonesia has, like the other neighbours of Malaysia, objected to the map.
