They already have a sufficient mastery in making surface fleet, mainly because they also have a robust and massive civilian shipbuilding industry (neck-to-neck with South Korea). Their next target probably is to master making submarine and nuclear propulsion. What I am looking forward is that assuming Chinese battery maker managed to lead the world both in research and manufacturing because massive Chinese Electric Vehicle growth, will it helps Chinese's submarine and drone development?
