Malaysia is a Southeast Asian country consisting of two non-contiguous regions: Peninsular Malaysia and East Malaysia (located on the island of Borneo), separated by the South China Sea. Kuala Lumpur is the capital and largest city, while Putrajaya serves as the administrative center. Peninsular Malaysia shares a land border with Thailand and is connected by bridges to Singapore. East Malaysia borders Indonesia and Brunei. A key geographical feature is the Strait of Malacca, one of the most important shipping lanes in the world, separating Peninsular Malaysia from the Indonesian island of Sumatra. Malaysia is known for its tropical rainforests, some of which are among the oldest in the world (like Taman Negara). Mount Kinabalu in Sabah is the highest peak in the country. The climate is equatorial, characterized by high temperatures and humidity year-round. It is a megadiverse country with a high number of endemic species, including the orangutan found in Borneo.
