N, S Korea refuse to face each other; play semis as 1 team
North and South Korea decided not to face each other in quarter-finals and instead fielded a joint women's team for the semi-finals against Japan at the 2018 World Table Tennis Championships. The teams did not want to clash amid the inter-Korean reconciliation while ITTF agreed to change the rules saying "it's more than a sport, it's more for the peace".
