To be Anti-China is basically the same as being Anti-semitic or Anti-Islam; it's just old fashioned Racism for the New Century. Old Habits die hard.

Many, many people in Australia, USA, and other basically Euro-pop places used to hate the Chinese because they were terrified of these millions of poor flowing in, in 'yellow hordes' , overwhelming them, over-whelming us all.
Now a lot of people hate the Chinese because they are doing really well and really don't fundamentally need anyone else to keep doing well, and we desperately need them.
Times have changed and yet Hate is Hate and the fear of China is now what it always was: Racism.
