Borneo
Malaysian Borneo occupies the northern part of Borneo, the world's third-largest island, and consists of the states of Sabah and Sarawak together with the federal territory of Labuan. The region is marked by extensive rainforests, rivers, mountains, limestone formations, and a long coastline along the South China, Sulu, and Celebes seas. Kota Kinabalu and Kuching are the principal urban centers, while smaller communities extend into forest and river regions.
