Economy of North Korea
Estimating gross national product in North Korea is a difficult task because of a dearth of economic data and the problem of choosing an appropriate rate of exchange for the North Korean won, the nonconvertible North Korean currency. The South Korean government's estimate placed North Korea's GNP in 1991 at US$22.9 billion, or US$1,038 per capita. In contrast, South Korea posted US$237.9 billion of GNP and a per capita income of US$5,569 in 1991. North Korea's GNP in 1991 showed a 5.2% decline from 1989, and preliminary indications were that the decline would continue. South Korea's GNP, by contrast, expanded by 9.3% and 8.4%, respectively, in 1990 and 1991.
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.
