Than that's more of a PR and sales issue than an engine R&D issue. Business reputation can only go so far.

Hence China's technological gap with the leaders in turbofan technology. China won't join them until the remaining few links are forged.
China dislikes being reliant on other countries for crucial technologies. There always needs to be a domestic, though not necessarily the most cost-effective alternative, to any piece of technology that is critical to China's national security. History has shown, time and time again, that even allowing an ostensibly non-hostile country to have her hands around your balls in wartime is a horrendous idea.
Guys, please return to topic!!!
This was even confirmed on the manufacture's HP ... have to look where again !
By the way ... as explained yesterday, this discussion has reached an end and arguments around how fine the F119 and F135 is are off-topic !

That is exactly what happen. Canada, England and Japan are only making sub-assemblies, not the entire engine. That's lack of technology. The US looks for partners to spread out costs, that's a hint of lack of capitals.USA, England, Canada seek cooperation because of deficiency in capital, technology
same Japan and USA seek cooperation because of deficiency in capital and technology
China both makes all components in the jet engine and continues to invest in improvements of those components. With exceptions of US and England, China is already doing a lot more than all other countries can do already. A entity that does more is in no way behind by any correct definition, unlike what some like to suggest.

Which engines are you talking about civilian or military?
I recall PRC import whole made engine in both areas.

What I said is absolutely true. US didn't receive any collaboration on the F-119. Going off tangent with "tour of world engines" is just your usual fallacy of in order to drag on your view that has been debunked.
It is a small engine, which China has no trouble coming up with an equivalent known as Minshan. See
You can't be more mislead if you truly believe what you have wrote. Japan XF-7-10 only has half as much thrust as WS-20. Japan has no WS-10 equivalent, and is even further from a F-119 equivalent than China is.

Military, and specifically WS-10. Imported engines either get indigenized or merely serve as interim solution. Importing does not negate the fact that China already has all the links in the chain required to produce jet engines, which is already more than what most nations have.
Civilian engines have geopolitical factors involved, not just technology factors. Let's just say if China has an equivalent of GEnx, China would still have no share of the civilian aero-engine market.
Chinese engine industry is clearly behind western companies like GE, P&W, RR, Safran. While it may pass Russians and Ukrainians in the future, it's also currently behind them. Saying that it's not behind these countries because it has a whole portfolio of products only means it has more projects. It's still behind those countries in terms of technology.
Saying England only makes sub assemblies is entirely laughable. Half of the wide body airliners use Rolls Royce engines.

That's false dichotomy. Achievement is an incremental process, not a binary process where you go from 0% to 100% after certain time criteria has been fulfilled. Hence jet engine development is analogous with forging a chain, and the one who got more links completed is obviously ahead of those with less links forged.
