Please de-politicize comments on C919 issue.
I'm betting money that the C919 LEAP engines will be sanctioned sometime between now and 2024 if there aren't significant Boeing orders going forward. Once that happens, what's going on in the semicon industry is going to happen to the aerospace industry. It's almost like America wants to sell nothing but soybeans.
This is true for every aviation item China is currently building: J-10, J-16, J-20, Y-20, Z-10... They all have superb craftmanship.
