Okay... let me get this straight. You are denying the fact that china has copied weapons from other countries.
I'm quoting a list which follows. Along with the weapon I think they have been copied from. Let's see whether you agree to it or deny it.
Type 56 Assault rifle =================== Russian Ak-47 and AKM
Norinco CQ ========================== American M-16
Chengdu Pterodactyl ===================== American Predator drone.
J-11 Fighter =========================== Sukhoi Su-27
J-7 ======================== Mig-21
Type 58 tank ================= Soviet T-34
Type 59 tank ================= Soviet T-54
J-20 Stealth fighter ============== Mig 1.44 Prototype
HArbin Z-9 ==================== AS365 Dauphin
There are more which I can quote but lets see you reply to these first.
