Beijng and other Asian cities are much hotter more humid than Moscow, so they really need it. In Moscow, given the existing infrustructure and climate - more intense ventialtion should solve most of the problems. I do not mind if they air-condition stations at some point, but air-conditioning trains will probably not happen, unless they build entirely new lines with screen doors.
