Nearly a million Tibetan children live in state-run residential schools on the Tibetan plateau. Chinese authorities subject these children to a highly politicized curriculum designed to strip them of their mother tongue, sever their ties to their religion and culture, and methodically replace their Tibetan identity with a Chinese one. Children as young as four have been separated from their parents and enrolled in boarding kindergartens under a recruitment strategy based largely on coercion.
A "haven" is a place, not a people. And a haven usually describes a place that has favorable laws, regulations, or attitudes towards certain behaviors. To me that is a government since havens usually have laws to support that. For example, a tax haven is a place where laws and government are organized in a way to be favorable to tax evasion.
