The aim of the research is to understand the role of Chinese ethnic minorities in biobanking for which they are sampled genetically. This research hopes to gain a better understanding of the effects of the knowledge that genetic sampling (new genetic technology) generates. Apart from finding out how biobanking activities alter relations between ethnic groups and the state, and what commercial stakes are involved, it also aims to understand the social and cultural effects of these activities on the ethnic groups in question. In short, this research explores the cultural politics of commercial and scientific interests in biobanking activities among ethnic groups in Southwest China.
