China has definitely turned: on the list of airlines not hiring anymore don't forget Xiamen Air, which was one of the biggest in terms of expats community.
As mach85 said, CSA stopped recruiting NTRs...how many rated guys will they get now? doesn't seems to be a problem for them since they keep failing people (even at initial type ratings) and they do nothing to stop pilots from resign. The rsp deal is basically over (especially on 777fleet) with no new assignment even with plenty "official" slots available.
Talking with a famous recruiter, I was told that a (named here) airline will get rid of foreigners over the next 12months or so.
Having said that, we all know that market in China is very unstable and everything can change again very rapidly... since most of the time those massive recruitments are even based on market figures, but on personal decisions of some so called "leader / manager".
