Olympics organizers on Friday welcomed an agreement between North and South Korea to unite athletes at the upcoming Winter Games in Pyeongchang, and promised that "much more exciting initiatives" promoting Korean unity will emerge this weekend.

"Watch this space," International Olympic Committee presidential spokesman Mark Adams told The Associated Press in an interview, a day before a crucial meeting of Korean delegations at Olympics headquarters in Lausanne. He declined to elaborate, saying the decisions would come Saturday.

Referring to a detailed peace-making agreement between the rival countries announced Wednesday by South Korea's Unification Ministry, including a joint team in the women's hockey tournament, Adams said it was "great ... but these are discussions."

The agreement, which still requires approval by the IOC, would mark the first time the two national Olympic committees would be competing together in a single team.

"I can tell you that there will also be some much more exciting initiatives coming through as well tomorrow," Adams added Friday.

Apart from fielding a joint women's ice hockey team, Seoul's Unification Ministry said the two countries would march together under a blue and white "unification flag" depicting their peninsula in the Feb. 9 opening ceremony.

Some have questioned the fine print of the agreement announced by the two Koreas, saying it gives the combined hockey squad a far larger roster than any other national team.

Asked how the IOC planned to maintain the integrity of the sport, Adams said: "People would say that these are exceptional circumstances, and we need exceptional measures."

"This is about the Olympic spirit," Adams added. "And the Olympic spirit is about nations competing, athletes competing, and we will do our best make sure that it sends a signal that sport can improve the world."
