this guys use realy everything on feets exept tables

found this map on wikipedia showing the dispersal area of the asian black bear

Asian Black Bear (Ursus thibetanus) range (brown - extant, black - extinct, dark grey - presence uncertain)

and of course it was or is also in the chinese mainland. some kind of bear must be living there and this is not the european brown.
surprising the himalayan bear live in the south of iran, to my knowledge a absolute hot and deserted area.

seems the amur leopard is NOT a target of the yellow chemists but maybe the bones were sold as tiger parts to greenhorns in the past.
