This article is about the foreign relations of Tuvalu. From 1916 to 1975, Tuvalu was part of the Gilbert and Ellice Islands colony of the United Kingdom. A referendum was held in 1974 to determine whether the Gilbert Islands and Ellice Islands should each have their own administration. As a consequence of the referendum, the separate British colonies of Kiribati and Tuvalu were formed. Tuvalu became fully independent as a sovereign state within the Commonwealth on 1 October 1978. On 5 September 2000, Tuvalu became the 189th member of the United Nations.
