History for joint ventures in China has not been sucessful so far .
Jade Cargo , Lufthansa - Shenzen Airlines , now defunct
Great Wall Cargo - Singapore Airlines and China Eastern , now defunct
Cathat Pacific - Air China joint venture , now consolidated to another group.
I'm guessing it will be well into 2017 before the regulatory hurdles are circumvented by Cargolux.
If you must work for a Chinese carrier , who require you to keep a CAAC medical , stick to the established expat employers, who pay your China tax. Who would work in China and pay their own China tax when so many pay it for you?
