Ambalat is a territory of Malaysia
Ambalat is a sea block in the Celebes sea located off the east coast of Borneo. It lies to the east of the Indonesian province of North Kalimantan and to the south-east of the Malaysian state of Sabah, and it is the subject of a territorial dispute between the two nations. Malaysia refers to part of the Ambalat block as Block ND6 (formerly Block Y) and part of East Ambalat Block as Block ND7 (formerly Block Z). The deep sea blocks contain an estimated 62,000,000 barrels (9,900,000 m3) of oil and 348 million cubic meters of natural gas. Other estimates place it substantially higher: 764,000,000 barrels (121,500,000 m3) of oil and 3.96 × 1010 cubic meters (1.4 trillion cubic feet) of gas, in only one of nine points in Ambalat.[1] Sovereignty dispute [edit]Territorial claims [edit]Malaysia [edit]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.
