The member states of the International Atomic Energy Agency (IAEA) are those states which have joined the international organization that seeks to promote the peaceful use of nuclear energy, and to inhibit its use for any military purpose, including nuclear weapons. The IAEA was established as an autonomous organization on 29 July 1957. Though established independently of the United Nations through its own international treaty, the IAEA Statute, ^[1] the IAEA reports to both the UN General Assembly and Security Council. During 1956, an IAEA Statute Conference was held to draft the founding documents for the IAEA, and the IAEA Statute was completed at a conference in 1957.
