Maritime borders

Malaysia has common maritime boundaries with

, the

and

. Part of its maritime borders have been delimited through agreements with neighbouring countries. Malaysia has agreements to delimit the continental shelf, territorial sea and other border delimitation agreements or treaties with Indonesia, the Philippines, Thailand and Singapore. Malaysia has also unilaterally declared its maritime boundaries through a 1979 map published by its Department of Mapping and Survey. The continental shelf and territorial sea limits depicted on the 1979 map have not been recognised by Malaysia's neighbouring states and have been the subject of maritime boundary and territorial disputes. Malaysia has signed joint development agreements for areas which are subject to overlapping claims with Thailand and Vietnam. Malaysia has signed a Letters of Exchange with Brunei in 2009 to solve the dispute of maritime territories between the two countries. The boundaries between the two countries currently follow those determined through pre-independence British Orders in Council.

Territorial waters off the coast of Peninsula Malaysia border Thailand to the north in the Straits of Malacca and South China Sea/Gulf of Thailand; Indonesia to the west in the Straits of Malacca and south east in the South China Sea; and Vietnam in the north east in the South China Sea.

Disputes

Outside the border defined by a 1995 agreement, there is still no formal agreement between Malaysia and

to delimit their common borders and this has resulted in several overlapping claims. Singapore claims a three-nautical-mile (6 km) territorial sea limit, while Malaysia claims a territorial sea limit. Following the
