:Here is a guy who claims that the ROC's constitution does not "indeed claim Mongolia", though ("Given that the Constitution's definition of "existing national boundaries" is vague, it is overly subjective to say with certainty that the boundaries of the ROC encompass "Outer Mongolia." It will take an amendment to the Constitution by the Legislative Yuan or interpretation of it by the Judicial Yuan to obtain an unequivocal answer.").  Of course we can write "some people claim the ROC claims", or that "some consider the foreign ministry's statement unconstitutional", but unless there is a court ruling or some other higher authority who sais it is, it seems a bit like OR to claim that the ROC constitution "does indeed claim Mongolia". We can see the constitution does mention Mongolian banners and leagues (?) in three articles, but in the same articles it also mentions Chinese citizens residing abroad - obviously "abroad" is not part of the ROC, either?
