I decided to create a list with aircrafts built in China, but looking confusingly similar to western types. I’m not generally claiming that they were copied. Some might have been built in license, some might use officially licensed parts.
This list will occasionally be updated. Please leave a comment if you know further types.
China Star CS2000
Looks like: Boeing 787
Looks like: Douglas DC-9 / McDonnell Douglas MD-80/90 / Boeing 717
Shanghai Y-10 (canceled in 1983)
Looks like: Boeing 707-320
Looks like: Antonov An-26
Looks like: Northrop F-20 Tigershark
Looks like: Israel IAI Lavi B
Looks like: Eurocopter AS-350 Ecureuil
Looks like: Aérospatiale Super Frelon
