There will also be no ceremony for the team event, won by Russia last week with 15-year-old Valieva playing a starring role.

The spectators will be separated from athletes and other people in the closed-loop by going in and out through specific gates and sitting in the designated area at Games venues.

Zhu Yi also took a tumble on Sunday in another section of the team event, coming last and almost costing the hosts a place in the final.

Though smaller in scale than the Summer Games, the Beijing Winter Olympics are being staged by a much more prosperous, powerful, confident and confrontational China.

Some spectators will be present at the opening ceremony but it is unclear how many.

Olympics chief Thomas Bach promises the governing body will support an inquiry if requested by Peng.

The US embassy meanwhile reiterates its position that Washington is not coordinating a global campaign regarding participation at the Olympics.

Their presence comes despite the US-led diplomatic boycott by countries including Britain, Canada, Australia and Denmark over China's rights record.

This is despite reporting fewer Covid-19 cases than the day before.

Beijing has detected a total of 55 local cases with symptoms since Jan 15, with both the Omicron and Delta variants.

People from high-risk areas are banned from leaving the city.
