China's top prosecutor, Zhang Jun, urged Xinjiang's authorities this month to extensively expand what the government calls the 'transformation through education' drive in an 'all-out effort' to fight separatism and extremism.
In a June 2017 paper published by a state-run journal, a researcher from Xinjiang's Communist Party School reported that most of 588 surveyed participants did not know what they had done wrong when they were sent to re-education. But by the time they were released, nearly all - 98.8 percent- had learned their mistakes, the paper said.
Transformation through education, the researcher concluded, 'is a permanent cure.'
