Easter Island was annexed by Chile

Easter Island was annexed by Chile on 9 September 1888, by Policarpo Toro, by means of the "Treaty of Annexation of the Island" (Tratado de Anexión de la isla). Toro, then representing the government of Chile signed with Atamu Tekena, designated "King" by the Chilean government after the paramount chief and his heir had died. The validity of this treaty is still contested by some Rapanui. Officially, Chile purchased the nearly all encompassing Mason-Brander sheep ranch, comprised from lands purchased from the descendants of Rapanui who died during the epidemics, and then claimed sovereignty over the island.
