Disneyland amusement park in Shanghai is temporarily closing after the Chinese city reported a new record of Covid-19 infections.
How long the closure will take depends on the authorities, the amusement park reported on Monday.
According to the Health Commission, more than 4,300 local infections and asymptomatic cases were identified nationwide on Sunday.
In China, several million people are in lockdown - cities have imposed full or partial curfews.
Among other things, metropolises such as Changchun, Shanghai, Shenzhen and Tangshan near Beijing are affected.
Multiple mass tests were carried out.
In Henan province, students at many colleges were not allowed to leave their campuses.
For more than two years, China's zero-Covid policy had weathered the pandemic fairly well, bringing outbreaks under control quickly.
However, numbers have skyrocketed since the arrival of the more widespread Omicron variant.
The authorities are now pursuing a "dynamic" strategy, imposing the strict measures in a more targeted and short-term manner to reduce the impact on the economy and everyday life.
However, the zero-Covid strategy failed in the hard-hit Chinese special administrative region of Hong Kong.
Government adviser and Hong Kong University (HKU) professor Yuen Kwok-yung estimated the number of infected at around 2.5 of the 7.5 million inhabitants, as reported by the South China Morning Post.
He does not expect that the virus could be eliminated.
Despite the high number of infections, the Hong Kong government sees the peak of the wave as over and announced easing.
The duration of the quarantine for incoming travelers will be reduced from 14 to 7 days from April 1st.
Aircraft from nine countries, including Great Britain, France and the USA, will then be allowed to land in the Asian economic and financial metropolis again.
