A growing number of foreigners from neighboring Cameroon, Nigeria, and Gabon have immigrated to the country. According to the ''Encyclopedia of the Stateless Nations'' (2002) 7% of Bioko islanders were Igbo, an ethnic group from southeastern Nigeria. Equatorial Guinea received Asians and native Africans from other countries as workers on cocoa and coffee plantations. Other black Africans came from Liberia, Angola, and Mozambique. Most of the Asian population is Chinese, with small numbers of Indians.
