Member states of the International Atomic Energy Agency explained

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.

Former member state

Four states have withdrawn from the IAEA at some point in the past, but three of them have since rejoined the AIEA. North Korea became a member in 1974,^[2] but withdrew in 1994 after the Board of Governors found it in non-compliance with its safeguards agreement and suspended most technical cooperation. Nicaragua became a member in 1957, withdrew its membership in 1970, and rejoined in 1977, Honduras joined in 1957, withdrew in 1967, and rejoined in 2003, while Cambodia joined in 1958, withdrew in 2003, and rejoined in 2009.
