Against China, there are more and more comparison with china these days, it will act very good as china is not a blue navy at all and the SNA would just destroy all the pseudo-frigate destroyer that china has. The of their ship is really bad. 20 years ago they made 0 ship and now they build 40 per years. It's impossible they have good quality ships, the fact they make lot of them proves that they are chosing quantity over quality. The recent Attack on US ship with chinese missiles shows how it's easy to jamm them.
How do you know that the quality of the Chines warships is bad? China has done a relly great job expanding their navy the last 10-15 years. I would say that in every way the chines has succeded. Thier building rate is almost in soviet 1980s numbers and they are making huge progress in AGEIS technology and engines. In the last decade they have commissioned over 10 destroyers, 20 frigates, 40 corvettes and have also started construct heavy aircraft carriers and missilecruisers.
If I were in the Russian Pacific Navy I would be worried.
