China has not catch up, China has been allowed to catch up by the west and by the collapse of the Soviet Union, but what is true for China is also true for India, Brazil or any emerging market, however key technologies like jet engines are highly guarded secrets, thus what China has been allowed to copy or learn is old technology, thus Today China still struggles with jet engine technology.
The Trent engines or 117s engines can not be simply copy, because some secrets are not available and are not easy to be obtain, plus these engines continue to be developed and new engines are already in the table thus copying cars or cell phones is not comparable to copy jet engines and while China can build some key technologies still is not allowed to enter the jet engine technologies that are the pillars of western aerospace dominance.

So, you are stating that the so called secrets cannot be discovered by China through research e developement but only "donated" by or copied from who already know these secrets.
Technology is not magical. What an organization or country is technologically capable depends on how strong it is in more fundamental sciences. Advantages in sciences held by one country is not insurmountable by another. Right now China's metallurgical and material sciences is still developing, but the rate of catch up for countries that can afford the resources is always greater than the rate of new advances.

You keep ignoring the obvious. Of course, China has not caught up. However, the fact that the gap between China and the West is now much narrower than that of 3 decades ago means that China is moving forward at a faster pace. Higher acceleration, if you will. We all know from basic physics, an object with a higher acceleration will eventually catch up to another object moving slower. That's just basic physics. All I'm trying to show you is that it is possible for someone falling behind to catch up. China is doing it now based on its track record for past 3 decades.
Again, yes! China has not caught up to the West yet, but it is narrowing the gap, which means it will eventually catch up. You can't argue with basic physics, unless you disagree with the Newtonian laws of physics.

China can do it, can re-invent any thing the west has done in the past but by the time they catch up with that stage, the west has moved ahead into a new technology.
Partnerships are to stay up to date but they require mutual respect and mutual interest like EJ-200 or other jet engine programs have.

I am not sure if you understood the replies by the other respondents. It does not matter to China or for that matter any nation, if they start off with an engine a generation behind in technology. The overriding concern is to develop an indigenous engine industry. Without a domestic engine, talk of catching up is moot. Just look at China's manned space program, which is well behind the American, European and Russian. But they got it going.
New advances happen slower than learning old ones.

Source for that? What's the point of 117 then? Russians spend all that time and money to develop it, specifically saying that it's different from AL-31, then they upgrade the AL-31 to match and then now still need to develop Izdeliye 30? Nice job. Let's see a source.
Clearly, you are not understanding what happened. Nobody "allowed" China to "catch up", especially not in the engine game. "Allowing" someone to catch up would be, giving someone the blueprints to the engine, teaching them the material sciences behind it, then teaching them how to mass-manufacture with quality control on them. Having China figure out all that by itself is not "allowing" anybody anything. Those technologies have always been deeply guarded as they are today.
You cannot seriously be at this level of understanding here. You are still at the logic of, "If runner A and runner B started at the same point but runner A took off first, then runner B will forever be behind because by the time runner B gets to the point runner A was at, runner A will have gotten further." It's called running faster, ok? Try running the 200 against Usain Bolt and have him start 3 seconds after you and you'll understand.
This reminds me of Zeno's Paradox, in which Zeno argued that a runner will never catch up to a tortoise because by the time the runner travels to the tortoise's previous location, the tortoise will have moved further away.
While Zeno's logic was sound, it was obviously incorrect. Likewise, China does not have to tail others in engine technology forever.
