Many other factors also affect an outcome of a battle. so although the PLAN are "brown water navy folks." they are well displined, trained and pack a punch.
I've studied the PLAN for over two years now. I am by no means an expert. But by my own personal standards(based on 20 years of service in the US navy) and after reading this very unbiased report by the USN intelligence..

The main reason is a lack of actual at sea time operating their equipment/training. Training = General quaters, firefighting ,damage control. Operating weapons systems. Spending time at sea so the sailors don't get "comfortable" in port. Ships are made for sea along with their sailors. It is my understaning for a good source that PLAN ships spen only about 30-45 days at sea a year. USN ships, in contrast, spend 168 days a year at sea. USN CV's spend more time that that at sea. Close to 180-190 days yearly when not in a re-fit cycle.
I also feel that the yearly assignment of new conscripts requiring the ships to remain in port from Nov-March yearly is a major disruption to training.
Blue water Navy? Hardly. I realize the PLAN does not have the comittments to deploy worldwide but the PLAN is seriously lacking in the ablity to deploy. There is a lack of foward bases. Which makes for a lack of logistics. There is a lack of logistic ships & helos....
Because any Navy has a lot of nice new ships does not mean they know how to operate theose ships.
Just my opinion based on my naval experience.
