A four-party meeting will be held  in Lausanne, Switzerland Saturday to discuss North Korea's participation in the PyeongChang Winter Olympics in South Korea.

Hosted by the International Olympic Committee(IOC) resident Thomas Bach, key officials from the two Korea's national Olympic committees and the PyeongChang organizing committee will finalize details related to North Korea's last minute decision to join the winter games.

During the meeting at the IOC headquarters, the four sides will seek to sort out a series of technical and procedural issues such as the size of the North Korean delegates and the sport events the North can send athletes to.

Ahead of the meeting, the Sion 2026 Olympics Bid Committee vice chairman Claude Stricker expressed his optimism on the North's participation.

"North Korea, I think it's a demonstration that the Olympic movement, the Olympic Games, the sport movement is also a tool for peace, and development of the relationships between the States. In any way, a good platform for dialogue."  

The meeting comes after the two Koreas agreed Wednesday to a joint marching of their athletes and the use of the unified flag of the Korean Peninsula during the opening ceremony of the Olympic games.
