As someone who has lived in China I can testify that this is a falsehood. The issue is getting the money out of the bank into some other asset in the first place. If you have that much purchasing power in a Chinese BTC exchange you probably already have a number of other means by which you can extract your money. The hard part isn't what to do with your money -- it's what to do with your money to get it out of the bank and get it into another asset. AFAIK it is not trivial to purchase that much BTC in China, so the level of attractiveness isn't as you assume.
