The Chinese variant of the former Soviet designed PMN antipersonnel mine is the Type 58.
Former Soviet manuals describing the PMN forbid troops to disarm this mine. They recommend that the mine be blown in place or exploded by mechanical means. This guidance has been demonstrated as sound by the number of fatalities associated with removal of the Type 58, and a variant produced by Iraq, from Iraqi minefields in Kuwait. Most fatalities occurred upon continued handling of mines with sand jamming the detonator/booster assemblies within the mine body.
Two noticeable differences from the original former Soviet version include the all black color and a slightly modified cover on the delay-arming device of the Chinese version. Any remaining features are identical to the original.
