Has anyone used their airline miles on a Chinese airline?

I am trying to fly from Guangzhou (CAN) to MDG in China. So far, I found out that China Southern airline which is a partner with Delta however they have no mileage seat at all at any time.

Does anyone know which Chinese airline in China has a partner with another airline that has award seats?

So far I have checked Air China who is a partner with US and UA/CO but they don't fly that route.

AA doesn't have any Chinese airline partners.

I would like to be able to use an award seat since the cash price is about $US900 round trip.

Any help would be appreciated.
