(5) The position of such States as Persia, Siam, China, Morocco, Abyssinia, and the like, is doubtful. These States are certainly civilised States, and Abyssinia is even a Christian State. However, their civilisation has not yet reached that condition which is necessary to enable their Governments and their population in every respect to understand and to carry out the command of the rules of International Law. On the other hand, international intercourse has widely arisen between these States and the States of the so-called Western civilisation. Many treaties have been concluded with them, and there is full diplomatic intercourse between them and the Western States. China, Persia, and Siam have even taken part in the Hague Peace Conferences. All of them make efforts to educate their populations, to introduce modern institutions, and thereby to raise their civilisation to the level of that of the Western. They will certainly succeed in this respect in the near future. But as yet they have not accomplished this task, and consequently they are not yet able to be received into the Family of Nations as full members. Although they are, as will be shown below (§ 103), for some parts within the circle of the Family of Nations, they remain for other parts outside. But the example of Japan can show them that it depends entirely upon their own efforts to be received as full members into that family.
(6) It must be mentioned that a State of quite a unique character, the former Congo Free State,[31] was, since the Berlin Conference of 1884-1885, a member of the Family of Nations. But it lost its membership in 1908 when it merged in Belgium by cession.
[Sidenote: Treatment of States outside the Family of Nations.]
§ 29. The Law of Nations as a law between States based on the common consent of the members of the Family of Nations naturally does not contain any rules concerning the intercourse with and treatment of such States as are outside that circle. That this intercourse and treatment ought to be regulated by the principles of Christian morality is obvious. But actually a practice frequently prevails which is not only contrary to Christian morality, but arbitrary and barbarous. Be that as it may, it is discretion, and not International Law, according to which the members of the Family of Nations deal with such States as still remain outside that family. But the United States of America apply, as far as possible, the rules of International Law to their relations with the Red Indians.
