China is the only country to purchase the productions rights to the SU-27 and follow on variants. Yup, that means they produce them indigenously and with their rather tenacious work ethic, you can bet they can mass produce them.
Actually, the first few that they assembled (not produced, but just put together kits the Russians sent them) were so poorly put together the Russians tore them apart and put them together themselves. They have gotten better but their aircraft industry is notorious for producing an extremely poor product.
Another thing is their pilot training. It just sucks. They are doing elementary stuff when we are doing doctorate level work. I can say from personal experience they are poor pilots. Maybe in 30 or 50 years they will be a threat but not anytime soon.
