It's intriguing to see that during the last 3 decades, China has made so much progress, and from a historical perspective, I think China will make its own plane, just like how they made their own cars and trains, I do think they have the ability to reverse engineer the plane related stuff,sooner or later, but innorvaton is another thing, it totally make sense to me that China wants to copycat all the high tech stuff, and also, the counter massure that US took is totally reasonable. From the human species' point of view, it is fascinating.
