The International Olympic Committee has opened a 2022 Winter Games bidding contest which has already lost an expected favourite.
Switzerland hoped to host its first Winter Games since 1948, but a regional referendum in March rejected the St. Moritz-Davos bid project as expensive and disruptive.
Norway's capital Oslo could be a strong candidate in campaigning that is likely to be conducted amid tough economic forecasts.
National Olympic bodies must propose host cities by Nov. 14, and formally apply by March.
The IOC says its executive board will select a candidates list in July 2014.
IOC members are scheduled to elect the host city on July 31, 2015, at their assembly in Kuala Lumpur, Malaysia.
The IOC also seeks bidders for the 2020 Youth Winter Games.
