SEOUL, South Korea — Despite the frosty political ties between their home countries, athletes from North and South Korea have sometimes produced emotional scenes of reconciliation at international sports events.

They tearfully hugged after winning a world table tennis championship, drew a standing ovation while parading together at the opening of the Olympics and took a selfie with each other that captured international headlines.

There could be similar drama at next month’s Winter Olympics in the South Korean ski resort town of Pyeongchang, with North Korean leader Kim Jong Un saying he’s willing to send a delegation to the games. The two Koreas will meet at their tense border on Tuesday to discuss how to cooperate on the Olympics.
