This is the typical entitlement mentality of the chinese government. They believe that they own you if your ethnic background happens to be chinese, no matter where you go in this world and no matter which country you have already become naturalized in. God forbid you have someone who immigrated when they were very young, NOPE you're still one of us and we give you the orders. In fact you MUST be gracious and grateful for no other reason because our government exists.

If you're Asian, chinese or not you better have loads of money if you expect to get treated like a human being. Otherwise you might as well not exist in their eyes. If you want to see walking dustballs just visit a government building. I remember I once had to teach an official how to write a simple chinese character when I was in a Foreign Experts Bureau since they forgot (too much baijiu)?

In the end, it's all about being in control. There isn't enough left of chinese "culture" in mainland china for any to see where one can actually experience something civilized on a consistent basis. All that's left is avarice and power.
