You're making yourself look foolish Bob - go and look up what an Air Identification zone is and you'll see, not one plane of China's has not encroached on Taiwan's airspace and, even if it had, it wouldn't be an encroachement because, legally, technically and geographically, Taiwan is part of China and, whilst I agree with you, it's not politically, it certainly isn't any of your business or mine how they resolve it between themselves but thank you for your comment and I hope you read it too because each time you do, it helps my algorithm build up stock
