Nothing to add, totally agree with this post.
During the cold war's era US created Cocom instance. This organisation tried to ban any sensitive western product to USSR in the goal to hamper soviet weapon's industry. The result was the exact contrary. USSR did not need western's technology.
Nowadays seeing what I see about the trade war, how can US allow a such transfert of technology that allow China to disput the challenge against US. Americans consider themselves as the arsenal of the democracies, they De Facto have the leadership of all West. What does it means ? It means if Germans, swiss, south koreans produce an innovative technologies, US consider that they are the owners, and they can decide who can trade with, who cannot trade. For that reason I have a doubt strong doubt about US agreements of such transfert. The fact that China developed from scratch its WS-10 it means China developed with its own. I suspect Russia helped China to overcome the WS-10's problem, that leads in fine to WS-15.
My first studies was mechanical engineering. The Jet engine is no more than the overcome of too much challenge, metallurgic's basis, tool machinery environnements, transport. But the foremost is the personal, it asks scientists that teach engineers, technicians and after the production. I think the WS-15 asked China to implement its own industiral basis, and chineses succeeded by their own.
I was told that "Chinese CNC penetration in industry is still low roughly 30% compare to 60 or 70% in Japan, Germany or Korea." It could be correct, but as western sources, and it depends witch client, for what, and where. Finally I suspect China is narrowing the gap with West in high level tool machinery, and maybe they are now equal else better than Japan and Swiss. To end my comment, Iam not chinese, I don't pretend to know better than you, however China became a superpower, and superpower in all areas, nothing can stop chineses to become the leaders in high CNC's technology.
