Ethnic Chinese in Brunei form roughly 15% of Brunei's population. As of 1986, it was estimated that over 90% were unable to obtain Bruneian citizenship despite generations of residence in the country. They constitute one group of Overseas Chinese and represent one of the more smaller groups of Overseas Chinese in Southeast Asia. Ethnic Chinese in Brunei were encouraged to settle because of their commercial and business acumen. The biggest dialect group is the Hokkien; many originated from Jinmen, Republic of China (Taiwan) and Xiamen in Mainland China. The Hakka and Cantonese represent a minority of the Chinese population. Despite their small numbers, the Hokkien have a considerable presence in Brunei's private and business sector, providing commercial and entrepreneurial expertise and often operating joint business ventures with Malaysian Chinese entreprises.
