The municipal government of South Korean capital Seoul on Thursday formally notified the International Olympic Committee (IOC) of its bid to co-host the 2032 Games with North Korea's Pyongyang, Yonhap news agency reported.
The IOC said in February that Brisbane was its preferred candidate to host the Games, adding it would enter "targeted dialogue" with the Australian bid organizers.
But the Seoul municipal government Thursday urged them to reconsider the bid for the two Koreas to co-host the Games, agreed to at a summit between South Korean President Moon Jae-in and North Korean leader Kim Jong Un in September 2018.
Yonhap reported Seoul's bid emphasized the peace-building potential of the co-hosting, as well as a "combination of cutting-edge technologies and Korean culture."
North Korea has not publicly commented on the bid, which comes amid markedly frosty relations between Seoul and Pyongyang.
The two have not held formal talks in over two years, and last week saw North Korean leader Kim Jong Un's influential sister slam the South's president as "a parrot raised by America" after he criticized a missile test by Pyongyang.
South Korea last hosted the Olympics in 2018, during which the two Koreas' teams marched under a united flag. North Korea has never hosted the Olympics.
