China said on Sunday that it had taken steps to prevent coronavirus cases from entering the country — over the top of the world’s tallest mountain.

Nyima Tsering, head of the Tibet Sports Bureau, told the state-run Xinhua News Agency that control measures would be put in place on Mount Everest, including the installation of a dividing line on the summit to prevent climbers from the Chinese side and the Nepal side from coming into contact.

Last week, a team of Sherpa guides affixed a rope to the summit of Mount Everest from the Nepal side, allowing expeditions to resume for the first time since the pandemic forced a cancellation of attempts last year.

Nepal has this year approved a record 408 permits to climb Everest, even as coronavirus cases have surged in the country and several climbers have been flown from base camp with symptoms of Covid-19.

China, which has approved just 21 permits to climb the mountain from its side this year, has expressed concern about the risk of coronavirus transmission on the mountain. Since the coronavirus first emerged in China in 2019, the country has carried out strict measures to prevent its spread internally and reintroduction from abroad.

The border between Nepal and China crosses the peak of Everest, a small area where a handful of climbers can stand after making a successful ascent.

At the summit, 29,031.7 feet above sea level, most climbers already wear masks to supply oxygen and protect themselves from the cold. But China will implement additional steps to reduce the risk of transmission.

In addition to restrictions on the summit, a checkpoint has been installed outside the Chinese base camp.

People returning from the Chinese side will have to undergo disinfection, temperature checks and potentially isolation, Xinhua reported.
