What ethnic groups are dominant in Peru?

Peru is a multi-ethnic country, which has been formed by the integration of different nationalities in the past five centuries. Before the Spanish colonial rule, Indians lived in Peru for thousands of years, but due to the spread of infectious diseases, their population dropped from about 9 million in the 1960s to 600,000. During the colonial rule, Spaniards and Africans flooded in and merged with the aborigines. After Peru's independence, European immigrants from Britain, France, Germany, Italy and Spain gradually settled down. After the abolition of slavery, China people began to work in the countryside in A.D. 1850 and became an influential nation. In 2008, Chinese in Peru accounted for about 10%, most of them were immigrants from Guangdong and Fujian, and some of them did not understand Chinese. Other immigrants include Arabs and Japanese.
