What is interesting is that, China had made advances in multiple areas in military technology from the very high tech (anti-satellite systems, JL-2, DF-31, anti-ship ballistic missiles, etc) to the lower technology system (Type-95 and a number of SMG... even the Type-99 MBT - consider low tech as compare to the anti-satellite system).
But they cannot come out with a decide sniper rifle? A decent ammunition for their sniper rifle? Whats the deal?
Limited resources (not just material resources, but largely actual talents). China, very much like Russia, focus on strategic weapon first - that's why most of the advances are focus on strategic parity. This gets filter down to tactical weapons, then crew use weapon
LAST. But as China advances in its industries, and education, it will eventually get more talents entering market that will help in this regards. Although I still believe Western countries will still be generations ahead.
The reason being : Weapon manufacturers face not much restriction setting up in western countries. Take for example, the relative "simple" pistol manufacturers. An average Joe in America could easily get a gun license (sometimes he doesn't even need to!), learn the trick of the trade in his spare time and start an small arm design business within a year! There are over
THOUSANDS of such companies in America (gunsmiths) - and also due to relaxed gun laws and the prevalent gun culture, it creates a large pool of talents consistently because of everyone's familiarity with gun. Where as in China, from what I understand, guns are strictly forbidden, which makes the understanding of gun, its use, and mechanism very limited to the general population. Without knowing the mechanism and its use, it makes the barrier entry into the industry extremely high - even if you get a very smart college graduate who has absolutely no experience with gun, he will find it hard to design a new and improved gun - much of his time will be just learning and retracing the steps of the past. The extremely strict rules regarding weapon manufacturers also stops organic growth of the arm industries (unless it's state approved/sponsored). There are less than 10 arm manufacturers that are known to the west (JS, Norico, Poly Technologies... just from the top of my head). This is why you see so few military technology improvement in this regard. Let's put it this way. Everyone loves eating and cooking in China right?
D) that's why you get top talents for cooking and lots of restaurants everywhere (almost to the point of every steps there is a eatery every 2 steps of the way in the city). Low entry requirement and huge rewards fuel this boom and the fierce competition creates top talents.
