Korea at the 2018 Winter Olympics
In January 2018, it was announced that the South Korea women's national ice hockey team would be amalgamated with a group of North Korean players to form a single Korea women's national ice hockey team in the tournament. They competed under the country code "COR", from the abbreviation of French word "Corée". (The country code “KOR” is already used for South Korea; the IOC uses “PRK” for North Korea.) The anthem which played when the Korea team played in international ice hockey is the folk song "Arirang" instead of the national anthems of either South Korea or North Korea. The team's uniform featured the silhouette of the Korean peninsula with the text "Korea". Because of ongoing U.S. sanctions against North Korea, the uniforms were made by a Finnish company instead of official sponsor Nike.
