The British Foreign Office has welcomed the next Friends of Yemen meeting, due to be held on 23 of May in Riyadh, Saudi Arabia. \"Yemen is facing a turbulent time, with serious security, political, economic and humanitarian challenges. As Yemen moves to formalise preparations for the second phase of transition, in particular national dialogue, we welcome the serious intent and determination expressed today. With our co-chair, Saudi Arabia, and alongside other members, we are committed to doing all we can to find concrete ways to support Yemen’s plans for reform, \" said a Foreign Office Spokesperson.
