The universal trade lanquage is primarily English because England commanded the oceans for so long and the US has run them since WW2, basically both English speaking countries that oversaw world trade. If Spain had won the battle of the Spanish Armada against Britain world trade language might be Spanish, or if France had beaten Britain it coulda been french. If China manages to command the oceans world trade lanquage might become Chinese.

It's basically based on wich ever nation commands the world trade routes.
