Shenzhen are interviewing mainly Brazilians. They currently have 4 or 5 Expats (Thru Contractair)
HNA have 2 (Australians) and expect to take many more expats within the next few months.
NB They have been promising to take lots of Lau Wai's for awhile. This time appears for real.
Air China and China Eastern have made a few moves in this direction as well.
If you are dealing with any company from mainland China: Don't call them China Airlines. No.1 shows your ignorance. No.2 Political reasons.
