There are a few companies which have FOs in China but I highly recommend to only come as a Captain. The upgrade is long, slow and painful here if it even ever happens. Most guys don't last that long. The cadet pilot program is alive and well in China and they normally produce a Captain from right out of college, 1 year doing license ratings and training ie private pilot, CPL etc. and type training. They then spend 4 years as an FO and upgrade is totally about 5 years time from start to finish. Chinese pilots are paid differently and not to the same standard as the ExPat Captains. China needs Captains not FO's so stay away, get your upgrade somewhere else then think about coming to China.
