Türkiye participates fully in both the Group of Western European and other States and the Group of Asia-Pacific States, but for electoral purposes is considered a member of the Group of Western European and other States only. As of 2010, Kiribati (geographically in Oceania) is not a member of any regional group, despite other Oceania nations belonging to the Group of Asia-Pacific States.
