> Is there a technology gap around that size, is that what you're saying? Yes, both a technological cap and a manufacturing gap. It's not just the size that's the issue, but the fact that the resulting plane must be fuel efficient. That's a very important factor that made a lot of damage to the A380 for example; it wasn't fuel efficient enough and many of its customers (middle east airlines) told Airbus they won't buy more until Airbus update it with better engines. Given that proper Engines manufacturing are also the issue for their fighter jets, it's easy to understand why China tries to get its end on any tech it can tech in that field (see: the old Tupolev and its tech they're buying from Ukraine, all the russian airframe they keep buying in small numbers, ...)
