Malaysia, country of Southeast Asia, lying just north of the Equator, that is composed of two noncontiguous regions: Peninsular Malaysia (Semenanjung Malaysia), also called West Malaysia (Malaysia Barat), which is on the Malay Peninsula, and East Malaysia (Malaysia Timur), which is on the island of Borneo. The Malaysian capital, Kuala Lumpur, lies in the western part of the peninsula, about 25 miles (40 km) from the coast; the administrative centre, Putrajaya, is located about 16 miles (25 km) south of the capital.

Climate
Both peninsular and insular Malaysia lie in the same tropical latitudes and are affected by similar airstreams. They have high temperatures and humidities, heavy rainfall, and a climatic year patterned around the northeast and southwest monsoons. The four seasons of the climatic year are the northeast monsoon (from November or December until March), the first intermonsoonal period (March to April or May), the southwest monsoon (May or June to September or early October), and the second intermonsoonal period (October to November). The onset and retreat of the two monsoons are not sharply defined.

Ethnic groups and languages
The Malay Peninsula and the northern coast of Borneo, both situated at the nexus of one of the major maritime trade routes of the world, have long been the meeting place of peoples from other parts of Asia. As a result, the population of Malaysia, like that of Southeast Asia as a whole, shows great ethnographic complexity. Helping to unite this diversity of peoples is the national language, a standardized form of Malay, officially called Bahasa Malaysia (formerly Bahasa Melayu). It is spoken to some degree by most communities, and it is the main medium of instruction in public primary and secondary schools.
