Since when did the American come to Australia and shower people with money? You probably watched too much TV. I do see Chinese fawning their money here in Australia, one time I actually saw an old Chinese guy shove money down a police officer outside a Chinese Restaurant, you can guess what happened next.
And yes, everything is a CIA conspiracy, and no, no matter how much government change, the current incumbent and showdown government are extremely anti-China, there were talks of even cancelling Australian Citizenship/Permanent Residence on some former Chinese national like the one with Huang Xiangmo. I don't see or hear anyone talking about cancelling Australian Citizenship of some US national.
If China want Australia to warm up with her, maybe she should stop "Demanding" the Aussie for respect?
