I don't know much about Chinese or N. Korean Special forces but I have talked to some Spetznaz.
They are pretty damn hardcore. Definitely not someone to meet in a dark alley. Much more emphasis on hand to hand, edged weapons, and martial arts than their western counterparts. They can do everything the western forces can but their some of their systems for commo, target designators, body armor, weapons, etc are pretty crude by our standards. They do come up with some interesting technical solutions though.
check out this weapon.
