third largest island in the world by area, located in south-east Asia

Borneo is the third largest island in the world. It is in the center of maritime southeast Asia. This island is part of three different countries. Indonesia, Malaysia and Brunei each have part of Borneo. Indonesia's region is called "Kalimantan" (although Indonesians use this word for the whole island). Malaysia's region of Borneo is called East Malaysia or Malaysian Borneo. The independent nation of Brunei is a small part of the island. Borneo has a rainforest that is in danger because it is valuable. Lumber companies cut trees here illegally.
