BEIJING - International Olympic Committee (IOC) president Thomas Bach has said that the Olympic Games is perhaps the most complex event on the planet, like a huge and difficult jigsaw puzzle.

For each Olympic Games, the IOC sets up a special Coordination Commission to work with the organizing committee on competitions, venues, media operations, accommodation, arrivals and departures, transport and registration.

Due in large part to the ongoing COVID-19 pandemic, the preparations for the Beijing 2022 Olympic Winter Games have been extremely difficult but received positive feedback from Juan Antonio Samaranch Jr., the Chairman of the IOC Coordination Commission for Beijing 2022 during an exclusive interview with Xinhua.
