Most of them are descendants of Southern Chinese immigrants who arrived in Malaysia between the early 19th and the mid-20th centuries. Malaysian Chinese form the second largest community of Overseas Chinese in the world, after Thai Chinese. Malaysian Chinese are traditionally dominant in the business sector of the Malaysian economy.
