The opening plenary, held under the theme "National Actions to Enhance Nuclear Security", was chaired by US President Barack Obama.

    The Summit, which brings together fifty countries in the US federal capital, offers the opportunity to examine means and mechanisms to reinforce nuclear security all over the world.

    The cycle of nuclear security summits was launched in April 2010 by President Obama. The first summit took place in Washington in 2010 while the second and third were held in Seoul and The Hague in 2012 and 2014 respectively.

    Morocco, which is among the few Arab and African countries taking part in this international event, plays an important role in the process of nuclear security summits.

    At the end of the opening plenary, HRH Prince Moulay Rachid and the other heads of delegations posed for a souvenir photo.
