For F/O's the Chinese CAA (CAAC) wil not recognize Co-pilot endorsements regardless of country of issue.
Your options then are to upgrade to a command rating (find a sim and examiner etc.. etc..), or to submit to the Initial type-rating course all over again.
I'm told this may take up to 6 months to complete,(ACC are desperately trying to shortcut this nonsense), and during this time you will be payed 50% of salary ie. USD 3,000 with no per diems. If you choose to reside in the flight-crew accom. building at the training facility across the road from the airport, you are charged RMB 6,000 p/m. ie 2 thousand more than your allowance. The building is 4 star hotel-type accom with all meals in cafeteria-style setup.
Should be a reasonable gig when the wrinkles are ironed out. This is the first time expats have gone through this neck of the woods, I believe, and there are new issues arrising weekly.
Stay tuned...
