The Khao-I-Dang (KID) Holding Center (Thai: เขาอีด่าง, Khmer: ខៅអ៊ីដាង) was a Cambodian refugee camp 20 km north of Aranyaprathet in Prachinburi (now Ta Phraya District, Sa Kaeo Province, Thailand).

According to Martin Barber, Chief of UNHCR's Kampuchean Unit, "The site, covering an area of 2.3 square kilometers on a gently sloping hill, had good drainage.

It opened...after just four days of preparatory work spent in establishing the overall design of the camp and developing the basic infrastructure (roads, water tanks, and latrines) of the first "chunk".

[3]: 77 On 19 October 1979, Thai Prime Minister Kriangsak Chomanan enacted an "open door" policy which permitted Cambodian refugees to cross the border safely and to reside in specific locations.

[9] In July and August 1980 UNHCR began transferring large numbers of refugees out of KID to Phanat Nikhom, Sa Kaeo II, Mairut, and Kap Choeng.

[3]: 16 Many Cambodians recall spending some time at KID, including Dr Haing S. Ngor of the film The Killing Fields, who (as a refugee) was employed in 1979 in the 400-bed ICRC hospital.

[20][21] ICRC chose KID for their first border surgical hospital where acute trauma patients were cared for, at first mainly war wounded, but later large numbers of landmine victims.

The ICRC hospital began treating patients on 27 November 1979 and during its first 54 days of operation 521 surgeries were performed, 162 of these related to war injuries, including 22 amputations.

[22]: 78 As of June 1984, the medical teams working at KID ICRC Hospital consisted of four surgeons, four anesthesiologists and 13 nurses sent by nine national Red Cross Societies: (Belgium, Finland, France, Iceland, Japan, Norway, Sweden, Switzerland, and the United Kingdom).

In response to international pressure, selection for resettlement of the residual population was extended again in 1988, after which Thai authorities officially decreed that all remaining refugees would be transferred to the border for repatriation to Cambodia.

[28] At the closing ceremony, then UNHCR Special Envoy Sérgio Vieira de Mello called KID a "powerful and tragic symbol" of the Cambodian exodus and the international humanitarian response.
