I would like to ask: How can major Western airlines manage to have state approval and insurance for routine operation in PRC if ATC safety-related performance, such as inability to deviate due CB etc, is so poor?
Good question but it is for the bean counters to address. But I would say if you want to fly to Country X you follow the rules of that country ,that said PRC non-deviation rules are not unique : look at the Afghanistan chart for instance . Deviate there and you risk to be shot down.
