During the Korean War, six countries—Sweden, India, Denmark, Norway, Italy, and West Germany—provided medical support to South Korea and the United Nations Forces. They provided a range of medical services, including the provision of mobile field hospitals; medical professionals, including doctors and nurses; hospital beds; equipment; and ambulances. Some of these personnel were killed during the conflict, though they were not combatants against North Korea and the People's Republic of China.

The Swedish Red Cross Field Hospital was established by the Swedish mission sent to Korea to deal with the humanitarian crisis. Following the North Korean invasion, the UN Security Council adopted a resolution asking all UN member states to support South Korea. The Swedish government responded on 14 July 1950, by authorizing the dispatch of a 200-bed mobile field hospital. ^{[citation needed]} Shortly before his death, King Gustaf V announced that the Swedish state would cover the hospital's expenses. The Swedish Red Cross Field Hospital personnel arrived in Korea on 23 September 1950, and began medical support on 25 September 1950.^{[citation needed]} Deciding that a stationary 400-bed Evacuation Hospital would be more valuable than the smaller but more mobile field hospital, which opened at the beginning of October, the Swedish hospital was converted and moved to the compound of the Commercial Middle School in Pusan, where it remained until 1958.^{[citation needed]}The hospital was expanded to 600 beds by the end of the war, staffed by 174 Swedish doctors and nurses at any one time, all belonging to the Swedish Red Cross.^{[citation needed]} Among its patients was the ROK Army Major Park Chung-in [ko].

After the ceasefire in July 1953, the institute changed its name to 'Swedish Hospital in Pusan'. The hospital stayed comparatively unchanged as a civilian hospital until it was closed in March 1957. The closing ceremony was held on 20 March 1957, and personnel left soon afterwards. A small advisory group from Sweden stayed in Korea to advise on medical practices until autumn 1958. Over the duration of the conflict, 1,124 Swedish men and women served in the Swedish hospital, and 19,100 United Nations and 2,400 Korean personnel were treated by Swedish doctors. ^{[citation needed]} At the closing ceremony, the hospital received the Republic of Korea Presidential Citation. Some personnel received the Korean Order of Military Merit.

Because of Sweden's reputation for neutrality during the major 20th century conflicts (First World, Second World and Korean Wars), Sweden was included as one of the four founding members of the Neutral Nations Supervisory Commission. Several Swedish military personnel served in Korea enforcing the Panmunjom armistice. Sweden was the first Western European country to establish diplomatic relations and an embassy in North Korea.

After the outbreak of the Korean War on 25 June 1950, India decided to provide a medical unit. The 60th Parachute Field Ambulance (60th PFA), commanded by Lieutenant Colonel A. G. Rangaraj, arrived on 20 November 1950 and began to operate on 6 December 1950 at the Pyongyang front. The main unit was attached to the British 27th Infantry Brigade and the 1st Commonwealth Division and provided medical support at the front, while the detachment served in the hospital at Daegu, providing services to the UN Forces, South Korean Army, and Korean civilians. Around 20,000 soldiers and civilians were treated from November 1950 to February 1954.

After Operation Tomahawk on 21 March 1951, for which the 60th PFA was attached to the 187th Airborne Regimental Combat Team, two members of the unit were awarded with the Maha Vir Chakras, while the 60th PFA was awarded the President's Trophy on 10 March 1955.

Indian Army officer—Colonel M. K..Unni Nayar, part of the United Nations Korea Committee, died on 12 August 1950 when he was killed in a mine accident. He was buried in Daegu, and his wife was interred in the same grave in 2012. A memorial to him in Suseong District, Daegu was unveiled on 7 December 1950.

Denmark supplied the MS Jutlandia under the Danish Red Cross for the duration of the war.^{[citation needed]}
