The nuclear security summit in The Hague drew to a close on Tuesday afternoon with the publication of the final communiqué.

The communiqué states that the 58 world leaders who took part made concrete agreements to stop terrorists getting their hands on nuclear material which further reduces the threat of a nuclear attack.

Among the new agreements are measures to reduce the amount of dangerous nuclear material in the world, to improve the security of radioactive material which can be used to make a ‘dirty’ bomb and to improve the international exchange of information and international cooperation.

The outcome of this nuclear security summit is ‘a major step towards a safer world’, the communiqué says.

Home

Not all the delegates stayed until the end. By early afternoon, several world leaders were heading home, including German chancellor Angel Merkel, French president François Hollande and Italian prime minister Matteo Renzi.

They did, however, attend the informal lunch catered by Jonnie and Thérèse Boer, owners of the three-star De Librije restaurant. The meal included a starter of cod from the North Sea with Dutch asparagus and a main dish of Dutch lamb with organic vegetables.

Prior to the lunch, the leaders also gathered for a group photo with host and Dutch prime minister Mark Rutte and US president Barack Obama front and centre.

Agreements

One agreement made earlier in the day by 32 of the participating countries was to allow experts from other countries to inspect their storage of nuclear waste.

Among them are the US and most of the EU countries. Russia and China are among those who refused to take part.

Also earlier in the day, Dutch foreign minister Frans Timmermans said that countries should do more to make the world nuclear weapons free. Timmermans said that the security of nuclear waste cannot be seen as separate from stock piles of nuclear weapons.

Obama remains in the Netherlands until later in the day. He has a series of meetings in The Hague before flying out to Belgium where he will visit various EU organisations on Wednesday.
