For what it's worth, a Taiwanese co-worker sent me the link, commenting along with it that in Japan we're too nice about this. In Taipei they raise hell when a mob of mainlanders behave like unruly five year old kids.

This is not about anti-Chinese sentiment at all. Spend five minutes talking to Chinese folks of Taiwan, Singapore, or Hong Kong, or you know what, even with Chinese studying or working in the West ( a part of the world which I am not a fan of, and less so every year ) and see what they tell you. This is a very specific issue about a very specific group of people in very specific circumstances.
