The Australian Chamber of Commerce in Shenzhen

The Australian Chamber of Commerce in Shenzhen, or "AustCham," as their homepage says, was organized to "provide Members the opportunity to enhance their knowledge of China and Australia and to assist in developing sound commercial relationships by expanding professional skills and business contacts through networking and business events."

It's not just for Aussies; it's "an inclusive organisation with a broad ranging constituency of both [Australian and Chinese] nationalities and commercial activities represented. The common link is a desire to develop and improve business relationships between Australia and China , with a particular focus on Shenzhen and the surrounding districts."

In addition, they sponsor social activities/networking event to which people of all nationalities are welcome.
