East Malaysia (
Malaysia Timur), also known as
Sabah, Sarawak and Labuan (
Sabah, Sarawak dan Labuan) or
Malaysian Borneo, is the part of
Malaysia located on the island of
Borneo. It consists of the
Malaysian states of
Sabah,
Sarawak, and
Federal Territory of
Labuan. It lies to the east of
Peninsular Malaysia (West Malaysia), which is located on the
Malay Peninsula. The two are separated by the
South China Sea. While East Malaysia is less populated and less developed than West Malaysia, its land mass is larger and it has notably more natural resources, chiefly oil and gas reserves.
