International law in the field of nuclear security is composed of not only treaties such as ammended Convention on the Physical Protection of Nuclear Material, but also soft laws such as Nuclear Securiry Series published by IAEA, which may provide the guidance to the Member States in order to construct the physical protection of muclear facilities. There are also the cases of soft laws to show the futute direction, for example, Nuclear security summits declaration. In this presentation, I would like to explain why the international law, especially soft laws, in the field of nuclear security plays a comprementary role to the related treaties.
