In the East Malaysian states of Sabah and Sarawak, there have been many incidents of intermarriage between Chinese and native tribes such as the Murut and Dusun in Sabah and the Iban and Bisaya in Sarawak. This phenomenon has resulted in a potpourri of cultures in both states where many people claiming to be of native descent have some Chinese blood in them, and many Chinese have native blood in them. The offspring of these mixed marriages are called "Sino-(name of tribe)", e.g. Sino-Dusun. Normally, if the father is Chinese, the offspring will adopt Chinese culture and if the father is native then native culture will be adopted, but this is not always the case. These Sino-natives are usually fluent in Malay and English. A smaller number are able to speak Chinese dialects and Mandarin, especially those who have received education in vernacular Chinese schools.
