evidence: Ambalat [edit]Ambalat is an area of the seabed or continental shelf in the Celebes Sea off the east coast of Borneo which is claimed by Indonesia and Malaysia. The seabed is believed to be rich in crude oil. Contrary to popular belief, the International Court of Justice decision over the sovereignty of Sipadan and Ligitan did not solve the dispute over Ambalat as it did not include issues concerning the demarcation of the territorial sea and continental shelf boundaries of the two countries in the area.[23] The dispute started with Malaysia issuing a map in 1979 of its territorial sea and continental shelf which included the Ambalat block. The map drew Malaysia's maritime boundary in a southeast direction into the Celebes Sea after it leaves the eastmost point on land on Sebatik island. This would include the Ambalat block, or a large part of it, within the Malaysian continental shelf. Indonesia has, like the other neighbours of Malaysia, objected to the map. Indonesia has never officially announced the exact locations of its maritime boundaries but claimed during its arguments in the Sipadan Case that it continued in a straight line along the 4° 10' North latitude after it leaves Sebatik.
