现代国际法秩序产生以前,国家统一或分裂是以非文明的方式轮番上演;国际法秩序产生以后,国家统一或分裂就逐渐朝着文明的方向发展。国际法既保障了各主权国家领土边界的法律上的稳定性,也要求各主权国家在维护国家统一这种国内问题上,应采取和平方式或贯彻和平精神。 Before the emergence of the modern order of international law, the unification or division of state was staged in a non-civilized manner. After the birth of the international law order, the unification or division of the nation gradually moved toward the direction of civilization. International law not only guarantees the legal stability of the territorial borders of various sovereign countries, but also requires that sovereign states adopt a peaceful manner or implement the peace in the domestic issues of safeguarding national unity.
