Site Two Refugee Camp (also known as Site II or Site 2) was the largest refugee camp on the Thai-Cambodian border and, for several years, the largest refugee camp in Southeast Asia. The camp was established in January 1985 during the 1984-1985 Vietnamese dry-season offensive against guerrilla forces opposing Vietnam's occupation of Cambodia. Site Two was closed in mid-1993 and the great majority of its population was voluntarily returned to Cambodia.
