Indonesia–Singapore border
International maritime border between Indonesia and Singapore / From Wikipedia, the free encyclopedia
The Indonesia–Singapore border is a maritime boundary in the Straits of Singapore between Indonesia's Riau Islands which lie to the south of the border, and the islands of Singapore which lie to the north. The Straits of Singapore is one of the region's busiest waterways as it is the main channel for Singapore's ports.
Only a portion of the maritime border between the two countries has been determined. The remaining parts, especially those lying to the east of the delimited boundary, may require the involvement of Malaysia as the country also possesses territorial waters in the area.
