Borders of Malaysia

Except for its coastline with the South China Sea, Brunei is completely surrounded by Malaysia's state of Sarawak on the island of Borneo.

The Malaysian states of Kedah, Kelantan, Perak and Perlis border the Thai provinces of Narathiwat, Satun, Songkhla and Yala.

Malaysia has common maritime boundaries with Brunei, Indonesia, the Philippines, Singapore, Thailand and Vietnam.

Malaysia has signed joint development agreements for areas which are subject to overlapping claims with Thailand and Vietnam.

There is also a dispute involving the alleged incursion into Malaysian territorial waters by land reclamation works by Singapore at the western entrance to the Straits of Johor.
