United Nations Security Council
Along with the five permanent members, the Security Council of the United Nations has temporary members that hold their seats on a rotating basis by geographic region. Non-permanent members may be involved in global security briefings. In its first two decades, the Security Council had six non-permanent members, the first of which were Australia, Brazil, Egypt, Mexico, the Netherlands, and Poland. In 1965, the number of non-permanent members was expanded to ten.
United Nations Security Council Resolution 2270
The United Nations Security Council unanimously adopted Resolution 2270 on March 2, 2016, with approval of all the five permanent members and the ten non-permanent members in response to North Korea’s fourth nuclear test on January 6, 2016, and its launch of a long-range missile carrying what it said was a satellite on February 7, 2016.
