It could impact the Christians in China if they are.... One of the people I interviewed was a student who had been sent away. He was a student at one of the seminaries. He had been sent out of Chengdu and he wasn't able to come back. What kept happening was that as soon as he would buy a train ticker or plane ticket to come back, he would get called up and asked where he was trying to go. If he tried to go to the airport or the train station, police would be waiting for him there.

It seems to be operated through sort of disparate pilot projects across the country, so it's not really uniform, but the goal is to create a large supersystem where people are tracked and all their behaviour is tracked.
