evidence: Malaysia's maritime boundary in its 1979 map is not recognised by Singapore[8] and Singapore disputes many parts of the territorial sea and continental shelf claimed by Malaysia. Among them is a slice of territorial waters called the "Point 20 sliver" (see below), and previously, the sovereignty of Pulau Batu Puteh/Pedra Branca which lies within the 12-nautical-mile (22 km) territorial waters claimed by Malaysia but has since been decided by the International Court of Justice in Singapore's favour. [...] The Tuas development, however, can be deemed a case of territorial dispute as Malaysia claims the reclamation works has encroached into its territorial waters in an area called the "Point 20 sliver".[17] The "sliver", regarded as an anomaly by Singapore, arises as a result of the unilateral declaration of Malaysia's territorial waters boundary as defined by a 1979 map published by Malaysia where, between turning points No 19 and No 21, Point 20 strikes out to the east of the general continental shelf boundary towards Singapore, thus forming a triangle of Malaysian territorial waters extending eastwards from the general north–south territorial waters boundary. The Tuas development reclamation project encroaches into this sliver of territorial waters. Singapore does not recognise the 1979 continental shelf boundary and, thus, does not recognise the "point 20 sliver" as under Malaysian sovereignty.[18]
