<P> Under an historic agreement facilitated by the IOC, qualified athletes from North Korea were allowed to cross the Korean Demilitarized Zone into South Korea to compete in the Games . The two nations marched together under the Korean Unification Flag during the opening ceremony . A unified Korean team, consisting of 12 players from North Korea and 23 from South Korea, competed in the women's ice hockey tournament under a special IOC country code designation (COR) following talks in Panmunjom on 17 January 2018 . The two nations also participated separately: the South Korea team competed in every sport and the North Korea team competed in alpine skiing, cross-country skiing, figure skating and short track speed skating . See North Korea at the 2018 Winter Olympics for further details . </P> <P> On 5 December 2017, the IOC announced that the Russian Olympic Committee had been suspended due to the Russian doping controversy and the investigation into the 2014 Winter Olympics in Sochi . Individual Russian athletes, who qualified and could demonstrate they had complied with the IOC's doping regulations, were given the option to compete at the 2018 Games as "Olympic Athletes from Russia" (OAR) under the Olympic flag and with the Olympic anthem played at any ceremony . </P> <Table> <Tr> <Th_colspan="2"> (hide) Participating National Olympic Committees </Th> </Tr> <Tr> <Td_colspan="2"> <Ul> <Li> Albania (2) </Li> <Li> Andorra (5) </Li> <Li> Argentina (7) </Li> <Li> Armenia (3) </Li> <Li> Australia (50) </Li> <Li> Austria (105) </Li> <Li> Azerbaijan (1) </Li> <Li> Belarus (33) </Li> <Li> Belgium (22) </Li> <Li> Bermuda (1) </Li> <Li> Bolivia (2) </Li> <Li> Bosnia and Herzegovina (4) </Li> <Li> Brazil (9) </Li> <Li> Bulgaria (21) </Li> <Li> Canada (225) </Li> <Li> Chile (7) </Li> <Li> China (80) </Li> <Li> Chinese Taipei (4) </Li> <Li> Colombia (4) </Li> <Li> Croatia (19) </Li> <Li> Cyprus (1) </Li> <Li> Czech Republic (93) </Li> <Li> Denmark (17) </Li> <Li> East Timor (1) </Li> <Li> Ecuador (1) </Li> <Li> Eritrea (1) </Li> <Li> Estonia (22) </Li> <Li> Finland (100) </Li> <Li> France (106) </Li> <Li> Georgia (4) </Li> <Li> Germany (153) </Li> <Li> Ghana (1) </Li> <Li> Great Britain (58) </Li> <Li> Greece (4) </Li> <Li> Hong Kong (1) </Li> <Li> Hungary (19) </Li> <Li> Iceland (5) </Li> <Li> India (2) </Li> <Li> Iran (4) </Li> <Li> Ireland (5) </Li> <Li> Israel (10) </Li> <Li> Italy (120) </Li> <Li> Jamaica (3) </Li> <Li> Japan (124) </Li> <Li> Kazakhstan (46) </Li> <Li> Kenya (1) </Li> <Li> Korea (35) </Li> <Li> Kosovo (1) </Li> <Li> Kyrgyzstan (2) </Li> <Li> Latvia (34) </Li> <Li> Lebanon (3) </Li> <Li> Liechtenstein (3) </Li> <Li> Lithuania (9) </Li> <Li> Luxembourg (1) </Li> <Li> Macedonia (3) </Li> <Li> Madagascar (1) </Li> <Li> Malaysia (2) </Li> <Li> Malta (1) </Li> <Li> Mexico (4) </Li> <Li> Moldova (2) </Li> <Li> Monaco (4) </Li> <Li> Mongolia (2) </Li> <Li> Montenegro (3) </Li> <Li> Morocco (2) </Li> <Li> Netherlands (33) </Li> <Li> New Zealand (21) </Li> <Li> Nigeria (3) </Li> <Li> North Korea (10) </Li> <Li> Norway (109) </Li> <Li> Olympic Athletes from Russia (168) </Li> <Li> Pakistan (2) </Li> <Li> Philippines (2) </Li> <Li> Poland (62) </Li> <Li> Portugal (2) </Li> <Li> Puerto Rico (1) </Li> <Li> Romania (27) </Li> <Li> San Marino (1) </Li> <Li> Serbia (4) </Li> <Li> Singapore (1) </Li> <Li> Slovakia (56) </Li> <Li> Slovenia (71) </Li> <Li> South Africa (1) </Li> <Li> South Korea (122) (host nation) </Li> <Li> Spain (13) </Li> <Li> Sweden (116) </Li> <Li> Switzerland (166) </Li> <Li> Thailand (4) </Li> <Li> Togo (1) </Li> <Li> Tonga (1) </Li> <Li> Turkey (8) </Li> <Li> Ukraine (33) </Li> <Li> United States (241) </Li> <Li> Uzbekistan (2) </Li> </Ul> </Td> </Tr> <Tr> <Th> NOCs that participated in 2014, but not in 2018 . </Th> <Th> NOCs that participated in 2018, but not in 2014 . </Th> </Tr> <Tr> <Td> <Ul> <Li> British Virgin Islands </Li> <Li> Cayman Islands </Li> <Li> Dominica </Li> <Li> Nepal </Li> <Li> Paraguay </Li> <Li> Peru </Li> <Li> Russia </Li> <Li> Tajikistan </Li> <Li> Venezuela </Li> <Li> Virgin Islands </Li> <Li> Zimbabwe </Li> </Ul> </Td> <Td> <Ul> <Li> Bolivia </Li> <Li> Colombia </Li> <Li> Ecuador </Li> <Li> Eritrea </Li> <Li> Ghana </Li> <Li> Kenya </Li> <Li> Korea </Li> <Li> Kosovo </Li> <Li> Madagascar </Li> <Li> Malaysia </Li> <Li> Nigeria </Li> <Li> North Korea </Li> <Li> Olympic Athletes from Russia </Li> <Li> Puerto Rico </Li> <Li> Singapore </Li> <Li> South Africa </Li> </Ul> </Td> </Tr> </Table> <Tr> <Th_colspan="2"> (hide) Participating National Olympic Committees </Th> </Tr>
