It's a matter of time.
The Chinese however don't seem too anxious in mass building any of their current designs (like J-10, etc). They are clearly first trying to amass different skills and technologies, and when the time is right, they will start building like no tomorrow.
They are probably going to navalize their J-10's too soon.
No they'll probably go down the line of navalised Flankers with Frogfoots as their trainers.
