The reality with China is that because of the amount of Jeopardy which exists during the initial period and even for every annual medical (you only have to be unlucky and get the wrong doctor), China can not be recommended to Pilots who already have secure and half reasonable jobs in there own country, especially guys with families. A number of people who arrived from a national carrier at my company have recently been released, having failed checks.
Just to add that I have no knowledge of the Chinese taking First Officers, it seems to me that there is no shortage of First Officers. They want experienced Captains.
