Why do they call Malaysia Malaysia?

Malaysia used to be known as the Federation of Malaya ( Tanah Melayu ). In 1963 this name was changed to Malaysia after Singapore, and two North Borneon states Sarawak & Sabah together with fed of Malaya formed Malaysia on the 16th September 1963 (though Singapore left) The 'Malay' comes from the fact that the majority of Malaysia's population at the time were of the Malay race. The 'sia' was taken to represent Malaysia's diverse culture, with Malays, Chinese and Indians making up the population (add the sia to Malay and it sounds like the end of the name is Asia).
