China has near clones of the F-35 Lightning, the Comanche stealth helicopter, the best of Russia&#x27;s newest generation of tanks, etc.<p>I purchased a Trijicon ACOG clone from China for $136. It&#x27;s just as good as, if not better than (doesn&#x27;t require a battery for the chevron, and a battery powered chevron is, IMHO, not a good feature), the real thing, which costs civilians $1,400, and our military something like $800 each.<p>I can&#x27;t speak for the highest of the high tech, in terms of a &quot;wind down&quot;, but I can assure you that $47B in China will get you a LOT more than $47B will in the US, and the lack of R&amp;D costs is a big part of that.
