Some airlines, like Hainan, you might find yourself jumpseating and flying as an FO for over 300 hours for a Type-rated Captain position. The 320-330 deal at Hainan is new, and there is a real good chance they haven't sorted out the details with their local CAAC. God knows what requirements the CAAC will impose upon you.
This place is chaos in a lot of ways. The way the CAAC deals with Air China in Beijing, the the rules they impose, are vastly different than a different arm of the CAAC will impose on a different airline somewhere else. HTF knows what you will go thru if you apply for this position. The management at Hainan probably doesn't know either, and they will be using the first few as guinea pigs to find out.
Good luck to those who try.
