This is a strange article. I did not find anything that is a blocker for China. China is a relative new comer to jet engines and this technology is tightly guarded by incumbents and needs time to mature.
If China can master nuclear, space, chips, it seems a bit stretch to say they it is the Jer engines where they fail.
