米国オバマ大統領の主導で始まった核セキュリティサミットは2年毎に4回開催され、核セキュリティ強化に向けた国際的な取組の推進に大きな役割を果たしてきた。途中、ロシアの離脱等はあったものの、首脳レベルの会合は国際的にも国内的にも注目度が高く、これによって各国の核セキュリティ強化が大きく進んだと言えよう。したがって、このモメンタムをポスト核セキュリティサミットにおいても維持していく施策の確立が早急に望まれる。そうした背景を踏まえ、今後の核セキュリティ強化に向けた課題、核セキュリティサミット後の動向、日本の取組について概括する。

The series of Nuclear Security Summit, initiated by President Barack Obama, was held biennially, four times since 2010, and played an important role in promoting international efforts to enhance nuclear security. Despite Russia's refusal to participate in the fourth meeting, these summit-level meetings have gained both international and domestic attention, which have led to remarkable improvements in the field of nuclear security of each participating country. Therefore, there is an urgent need to take continuous measures to keep this momentum alive even after the final Nuclear Security Summit concluded in 2016. The challenges in strengthening nuclear security, prospects in the post-Nuclear Security Summit phase, as well as efforts and measures that Japan should pursue are investigated.
