On 23 April 2015, the then-20-year-old Prince Hussein became the youngest person ever to chair a UN Security Council session. During the meeting, the prince oversaw a debate about methods of preventing young people from joining extremist groups. Ban Ki-moon, the then-Secretary-General of the United Nations, said Hussein is "not yet 21 years old, but he is already a leader in the 21st century". The Security Council unanimously adopted Resolution 2250 titled "Maintenance of international peace and security"; the resolution was presented at the initiative of Jordan during the session Hussein presided over.
