South Korea expressed regret that its delegation of athletes at the Paris Olympics opening ceremony on Friday was introduced as from rival North Korea and has demanded assurances from organisers the mistake will not happen again. As the boat carrying South Korean athletes passed on the Seine, the announcer introduced them as the “Democratic People’s Republic of Korea” – the official name of North Korea – in French and English. The announcer used the same introduction when the North Korean delegation passed. “We express regret that the country was introduced as North Korea at the opening ceremony of the Paris Olympic Games when the athletes of the Republic of Korea were entering,” it said. North Korea, which is returning to the Games for the first time since Rio 2016, has sent 16 athletes.
