You literally can't open an account? That's bizarre.
In any case, transferring money out of China is legal up to, I believe, the equivalent of 50,000USD per yer, but that's for citizens. For non-citizens, you need a legal contract and tax receipts before you can do anything. With those in hand, and probably the FAO tagging along, you are eligible to exchange, as I recall, up to 70% of your earnings for foreign currency. I don't know off hand if the 50,000USD per year cap still applies. It might.
Or, long story short, as the honourable cruisemonkey mentions, a Chinese citizen who somehow came to be in possession of your money could send it to a foreign bank account, perhaps even your own.
