With more and more ships-of-the-line being commissioned, the PLAN has been using the 022s less and less for the past few years. They go out for the occasional patrol but otherwise mostly stay in port. They are too specialised for their role and are maintenance-heavy owing to their pump jet propulsion. 2017 should be about the time they start getting mothballed.
It was a little surprising to me because they built a lot of them (80-90 ships?). I thought they liked them...
