The inaugural Nuclear Security Summit ended on Wednesday following the adoption of a communiqué that vowed cooperation on the prevention of nuclear terrorism.

The statement was signed in Washington by the leaders of the 47 countries in attendance as well as the heads of the United Nations, the International Atomic Energy Agency (IAEA) and the European Union.

Made up of a preamble and 12 articles, the communiqué says that nuclear terrorism is one of the most challenging threats to international security and stressed the need to strengthen nuclear security and reduce the threat of nuclear terrorism.

The statement also reaffirmed the essential role of the IAEA in the international nuclear security framework and pledged the signatories' will to fully implement all existing nuclear security commitments.

The communiqué also recognized the need for cooperation among signatory states to effectively prevent and respond to incidents of illicit nuclear trafficking.

Top foreign media, including AFP, said that with the communiqué, the participants of the Nuclear Security Summit had made clear that they would watch North Korea’s nuclear programs more closely.
