I'm maintaining a quite successful business that sells virtual goods, with customers from both Americas and Europe. We have some happy customers from China, and given their enthusiastic feedback, I'm researching the ways to expand to that region. Yet, from sources I was able to get my hands on it seems the rules of running an eCommerce business in China are vastly different on almost every level.

Do you have any experience in expanding an eCommerce business to China? Are there any particular things to keep in mind?
