Could you explain why you think a neutral country would not have secrets? E.g. currently being neutral doesn't mean you don't have preparations on what to do if you get attacked (indeed, both sides in WW2 considered an invasion of Sweden) and would like to keep those secret. You want to keep your diplomatic strategies secret to avoid them being exploited against you. Being neutral does neither necessarily mean "you allow everyone to do whatever they want in your country" nor "you do not interact with the warring parties at all".
