the european and russian aerospave industries are far more advance than China, yet both of them unable to come up with F-22 and F-35 type aircraft.
		
		
	 
F-35 is a joint development between BAE and the American defense contractors.
We did make the harrier after all

			everything else is domestic, powerplant, avionics, weapons, radar etc...
		
		
	 
What I mean is that those things weren't built from the ground up, they're just built based on Russian development, but not always directly copies.

			Just cause the J-10 has airtakes on its belly like the F-16 doesnt make it a copy.
		
		
	 
I was refering to the IAI's Lavi.
	
	
		
		
			A car has four wheels does that mean all cars are copied??
		
		
	 
If I take a T-80 and turn it into a Type 99 then yes, it is merely a heavily modified version, with your own electronics etc.
Something like the Arjun is more of an example of a self-built tank.
	
	
The J-8 project was largely made possible due to the transfer of MiG-21 technology from the Soviet Union in 1961. However this aircraft lacked the speed, range, altitude, and radar capability the PLAAF needed in an all-weather interceptor. The nascent Chinese jet aircraft industry was mostly established with Soviet assistance and Chinese designers followed Soviet design methodology for the J-8. A Soviet experimental aircraft known as the Ye-152 "Flipper" with similar configuration may have influenced the J-8 layout, as did the Sukhoi Su-15 'Flagon-A' airframe.

Uses licensed Rolls-Royce Spey Mk202 engine copies.
	
	
If the rumour is correct the SD-10 has the electronics from the Raytheon-Motorola bid for the AIM-120 (which lost but Raytheon bought Hughes later on), either that or it's a re-boxed R-77 with a Chinese motor.
	
	
Under this ostensibly civilian program, various key Western helicopter manufacturers Eurocopter (rotor design,consultancy), Pratt & Whitney Canada (PT6C turboshaft) and Agusta Westland (transmission) was able to provide considerable technical assistance to the program.[3] The WZ-10 attack helicopter will enter active service in 2008.
