Satellite data sheds light on China’s detention facilities in Tibet

Exclusive: China appears to have expanded use of high-security prisons as tool of repression in Tibet, researchers say

There has been a pattern of increased activity in recent years at high-security detention facilities in Tibet, according to a new study measuring night-time lighting usage, suggesting a potential rise in harsher imprisonments by Chinese authorities.

The report, by the Rand Europe research institute, said the findings added rare new clues about the Chinese government’s “stability maintenance” policies of control in the highly securitised Tibetan Autonomous Region (TAR), which it described as an “information black hole”.
