It seems that the Asian Winter Games will return in 2029, after having disappeared for the 2021 and 2025 editions for some reason...
The only confirmed bidder is... Saudi Arabia.
The proposed location in Saudi Arabia is Trojena, a planned ski resort within the greater NEOM mega-project.
According to the Trojena project website, the ski resort would be located 50 km from the coast of the Gulf of Aqaba, within an elevation of 1500 - 2600 m, and has winter temperatures of "...below zero celsius...". It is scheduled to open in 2026.
The Trojena 2029 AWG bid already has international support, specifically from the UAE.
The 2029 AWG host is expected to be announced on October 4.
