Transitional justice has played an important role in recent historical democratization processes. In some democratic nations, transitional justice has focused on the state’s past oppression and assimilation of ethnic communities. The US, Canada, Australia and New Zealand have come to grips with the oppression of indigenous ethnic communities under government policies of the past.
Juan Chun-ta (阮俊達), a researcher specializing in indigenous affairs, has published a thesis titled Indigenous Peoples and Transitional Justice: An Ethnic Mainstreaming Perspective.
