"Constans, Camille (C.C.)" :
Each wikipédia has his own rules. Often the same than en:, but not everytime. I think each wikipedia must have his own rules. Respecting some choosed by the wikimedia fundation, npov for instance.
Each wp have its own customs, but should share the same rules, I guess.
In theory, each wp entry should be the perfect translation of the same entry in any language, don't you think ? (IMO encyclopedic goal is to try to reach universalism.)
Then, basic rules should be the same, and the Chinese NPOV is to be the same as French one or Rwandese one.
(I new in wp so feel free to correct my likely mistakes)
