The meeting point of the maritime territories between the three countries has not been determined. Eastern segment  The eastern continuation of the territorial waters border defined by the 1979 Malaysian map starts near the eastern terminus of the 1927 agreement border at "Point 22", whereby it goes westwards towards Singapore to "Point 23" before travelling southeasterly towards its southmost point at "Point 27". It then continues in a general easterly direction to meet the southern terminus of the Indonesia-Malaysia border as defined by their continental shelf boundary agreement of 1969. The Indonesia-Singapore border should intersect this boundary at some point but the meeting point of the maritime territories of the three countries has not been determined. Malaysia's maritime boundary in its 1979 map is not recognised by Singapore and Singapore disputes many parts of the territorial sea and continuental 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 territorial waters claimed by Malaysia but has since been decided by the International Court of Justice in Singapore's favour. With the award to Singapore of the sovereignty of the island, further determination of the maritime boundary between the two countries as well as with Indonesia whose territorial waters are also in the area, would have to be done to fill in the various gaps and determine the tripoints. The area around Pedra Branca is expected to be complicated. Pedra Branca lies beyond the three nautical mile (6 km) zone claimed by Singapore but within the zone claimed by Malaysia. Singapore has indicated that the Indonesia-Singapore and Malaysia–Singapore borders in this area would not run continuously from the waters adjacent to the main Singapore island to the Pedra Branca area and a stretch of the Indonesia-Malaysia border would lie in between. Further complications could arise by the awarding of Middle Rocks, which lies 0.6 nautical miles (1.5 km) south of Pedra Branca (i.e. away from the Johor coast), to Malaysia. A joint technical committee has been formed to determine the maritime border. The border between Malaysia and Singapore only came into existence in the 19th century with the establishment and subsequently, cession of the island to the British East India Company by the Sultanate of Johor in 1824. Prior to that, Singapore was an integral part of the Johor Sultanate and subsequently, the Johor-Riau Sultanate.
