Can you honestly name one thing that was invented there (in the last century that is)
While they didn't invent the modern submachinegun or semiauto handgun, the Chicoms have come up with some unique firearms in the last century. And neither did we invent the famous rifles used in the first part of the 20th century; the Krag was designed by a couple of Norwegians, the Springfield 1903 is a license-built Mauser, and our prized M249 & M240B are Belgian creations.
The Norinco Type-79 is one of, if not the, only gas-operated SMGs used on a wide scale, and is a totally homogenous design. I'd love to get my hands on one of these, which fire the hot little 7.62x25 at 500rpm. Not exactly a zip-gun, but from my own experiences I'd prefer a slower rate-of-fire in a subgun.
From what I've read on the in-tern-et, Norinco possibly developed the helical magazine for the Chang Feng SMG before Calico did, which would probably be the first case of someone "borrowing" an idea from the Chicoms.
And China's newest homegrown SMG is the JS Type-05. While FN was developing the 5.7x28mm cartridge for their P90, Jiang She was working on their own PDW, the 5.8x21mm Type-05. Maybe JS got their design-cues from FN, maybe not.
And a really interesting piece of equipment the Chicoms turned out for wet-work are the Type-64 & 67 intergrally silenced pistols, which fire a unique 7.65x17mm round, and are convertable from semiauto to a manual single-shot mag-fed assassin's tool.
And lastly, here's a Chicom handgun which features something that I've never seen or heard of on a Western design; the Norinco 77B, exhibiting it's one-finger slide-cycling mechanisim. Neato.
Now, whether or not one would need to do a massive amount of finger-curls to successfully cycle the slide is unknown, but it definitely is an original design.
