As Football says, are you prepared to pay company tax on your transfers? You may get around this by doing transfers slowly and then closing the company down within one year (say 11 months or so) but it will be still illegal obviously you have received cash for services or products rendered and with no real expenses it will be nearly 100% profit. You could do this but if you ever come back to HK you could be up for tax evasion or something.
Another option we were discussing about getting cash out of China was to develop a research project with a foreign company. This is for R&D of some product/service. Registered the contract with the right department allows you to get the bank approval to send cash out of the country.
I don't know which country you are talking about but that is one way that was put to me.
