Hosting the Olympic Games again would be great, but proceed with caution, sports experts warned as Beijing announced its ambition to host the 2022 Winter Olympic Games.

Five years after the spectacular 2008 Summer Olympics, the Chinese Olympic Committee announced on Tuesday that Beijing and the nearby city of Zhangjiakou in Hebei province will launch a joint bid to host the 2022 Winter Olympics.

If the bid is successful, Beijing will become the first city in the world to host both the Summer and Winter Games.
