The IOC entrusts the honour and responsibility of hosting the Games to a host elected by the IOC Session. The organisation for the Games is based on a partnership between the IOC and the Organising Committee for the Olympic Games (OCOG).
The Olympic Games are the exclusive property of the IOC, which is the supreme authority for all matters concerning the Games. Its role is to supervise, support and monitor the organisation of the Games; ensure that they run smoothly; and make sure that the rules of the Olympic Charter and the Olympic Host Contract are respected. It is also the IOC that issues the invitation to NOCs to participate.
