JAH,
Good luck in your search for GA in the S/China area, chicken lips and rocking horse s**t is easier to come by. I researched the butt out of the area and ended up doing my PPL and still subsequent jolly flying in the PI's, cheaper, unrestricted airspace. The club is great and has a few AC. You could finish your PPL there and convert it to whatever later (The PI's are ICAO members). In Manila there is one FAA CFII but he is expensive.
The HK club is expensive and hard to schedule flights (in tight airspace to boot).
Ref the guy from Texas, he mucks about with a club in Zhuhai that has a few C172R's run by some ex-PLAAF guys.
Hope this helps mate.
Rgds.
