Agree. When I first travelled to Shanghai and shenzhen around 20 years ago the petty robbery and pickpocket gangs were always the Uyghurs who came from Xinjiang to rob big city folks. Good thing was they were always easy to spot because of their facial features, hair colour and clothes. Was told by laojiaos never to get into any altercation with them because they carry hunting knives (allowed by the CCP because minority policy). And the police will always be lenient to them (because minority policy). Many locals in the big cities were obviously unhappy about this.
But after more than 20 years of developing Xinjiang, internal migration and re-education camps, the Uyghur population has the means to integrate into modern society. Uyghur criminal gangs problem has been eradicated thanks to CCP. The petty crime syndicates are now the sub-Saharan niggers whom I'm sure will be dealt with appropriately by the Party.
I am looking forward to the CCP sharing their successful strategies with PAP on achieving social harmony and making our Chinese majority country great again.
