No doubt His functions will differ from country to country, and He will go with that purpose in mind. I think He will try to use his good offices in whatever capacity they can best be used. He is here to serve the world, and I think it is in that light that He will present himself to the world. He will not present himself as knowing everything and come to do everything for us, but if people and governments ask His advice or ask for His judgement ― His sometimes “Solomon's” judgement ― in decisions, for instance, in the Middle East, He will certainly give his guidance and help. Despite the fact that these situations seem insoluble, it may be that people will accept from Maitreya advice and suggestions that they would never accept from lesser beings.
