The Japanese Navy would hand them their ass.
Oh, yeah. Do NOT mess with the JMSDF. Compared to them the Chinese are still paddling in the kiddie pool.
Thanks for the mention. I was wondering how capable they
are. (the Japanese)
Most definitely, the Chinese Navy has little experience, untested hardware, flimsy ships and would lose bigly if fighting the Japanese Navy. Japan has over a century of naval experience against superpowers (Russia, etc.).
