Snow levels in mountains near Beijing will be sufficient for the 2022 Olympic Winter Games if China's capital wins the right to host the sporting event, an official of the country's bid committee said.

Some have voiced concerns that the mountains near Zhangjiakou, about 200 km northwest of Beijing, would not receive enough snow for an Olympic competition, requiring costly snow-making efforts.

If Beijing succeeds in its bid it will become the first city to host the Summer and Winter Olympics — and both within 14 years.
