Indonesia and Singapore face each other across the Singapore Strait and over the past fifty years have established several maritime boundary segments through these waters. The central portion of the boundary was delimited in 1973 with extensions added to the west and east in 2009 and 2014, respectively. As currently defined, the maritime boundary extends for 36 nautical miles and delimits the overlapping territorial sea entitlements of these two States. The boundary between Indonesia and Singapore will need to be extended in both the east and west to complete their maritime boundary and establish tripoints at both ends with Malaysia.
