'Sustainability' key for 2022 Winter Olympics

Organizers say the event must leave a legacy for future generations, as Sun Xiaochen reports.

As the Olympic spotlight shifts to Beijing following the Games in Pyeongchang, the Chinese capital has beefed up efforts to produce a sustainable Winter Olympics in 2022, with its legacy underlined as a key requirement for post-Games success.

Since the curtain fell on the 2018 Pyeongchang Winter Olympics in the Republic of Korea last month, Beijing has taken center stage to prepare for its own version of the sporting gala against the backdrop of a national plan to build a burgeoning winter sports industry leading up to 2022 and beyond.
