New PLAN vessels are built to a very high quality commensurate with Chinese advances in shipbuilding. It will take a loooong time for the 054A hulls to deteriorate to a degree where the PLAN feels comfortable retiring them. By then, the 054A will be sorely obsolete and the PN would be better off just asking China to build them brand new 057s/054Bs or allow ToT for Pakistan to build it domestically.
Yup, just like now PN is getting new 054As rather going for remaing 053s or 054s....
