I don´t know the right answer. Making some speculations, I can guess that chinese spear, queen of arms for martial artists, had one difference with the west one. The pole, made of bamboo gave it the flexibility that her european sister didn´t have. And this flexibility, combined with the long range, made of this weapon something fearsome in skilfull hands.
I think bow and arrow weren´t either an important arm between ancient europeans, except a famous Saxon archers corp, but japanese people made of bow and arrow a whole art, the kyudo (the way of the bow).
