Ammon News - AMMONNEWS - His Majesty King Abdullah returned home Saturday at the end of a working trip to Washington, where he joined world leaders at the nuclear security summit.

The summit's closing session stressed the need to build an integrated system to promote nuclear security at the national, regional and international levels, including expanding the scope of endorsing atomic safety legislations and implementing these laws.

The King, accompanied by His Royal Highness crown Prince Hussein, attended the opening session on national efforts to boost nuclear security as well as cooperation to transfer the expertise of individual countries in handling nuclear materials and technical know-how to the rest of world nations with the aim of developing advanced national programmes.

In an address to a White House dinner banquet hosted by US President Barack Obama to the delegations taking part in the summit, King Abdullah stressed the importance that the summit pursues efforts to come up with a permanent mechanism to maximize achievements and efforts exerted in the field of nuclear security.

"The size of risks we face is tremendous", the king said, referring to fears in the Middle East of the potential of the proliferation of nuclear, chemical, biological and radioactive materials, and adding that the chaos in the region had raised the risks that these materials and related technologies could be transferred to terrorist organisations. On the sidelines of the summit, King Abdullah held separate meetings with Japanese Prime Minister Shenzo Abe, Dutch Prime Minister Mark Rutte and Thai premier Prayuth Chan-ocha on developments in the Middle East, including efforts to achieve peace in the region and combat terrorism.

The talks also dealt with the Syrian crisis and aid to countries hosting Syrian refugees, including Jordan, as well as ways to follow up on implementing the decisions adopted at a recent donor conference held in London.
