Beijing has submitted an offer to host the 2022 WINTER Olympics. I don't think they have a snowball's chance against Almaty Kazakhstan, Krakow Poland, Lviv Ukraine, Oslo Norway, and Stockholm Sweden. 2018 is going to be in South Korea so China is too close. I think the rule is that only Europe can hold consequtive games
My money is on Oslo.
If they do win, then Beijing would be the first city to host both a Winter and Summer Olympiad
