I look at it this way - chinese are new, russian are used.
There are some manufacturing differences between the two which is namely reducing manufacturing costs. The Russian ones are fully milled everything. The Chinese ones started stamping SOME parts like the trigger guard and welding them on instead of milling from a solid block of steel but overall all the important parts on the military ones are milled on any I've seen(the SKS-d is a civilian version for export made in the 80's I believe and has things like a stamped reciever...this is not military). The biggest difference comes in the later ones where the chinese started to pin the barrels on rather than threading them. Theoretically I'd say the pinned barrel is more accurate due to perfect mating with the receiver and the only functional difference should be if one wants to swap the barrel out as the pinned will require a press while the threaded doesn't. Also all Chinese ones have a chrome bore, only late manufacture Russian ones are chrome lined.
