After second wave of Covid-19 wrecked havoc across the globe, the threat of the third wave still persists. To prevent such an eventuality, China locked down its Lanzhou city on Tuesday.
Media reports suggest that the lockdown was imposed after detection of 29 new domestic infections including six cases in Lanzhou. The entry and exit of residents would be strictly controlled and access will be there only for limited essential supplies or medical treatment. China's latest outbreak has been linked to the contagious Delta variant.
Earlier on Monday, China put thousands of people in northern China under strict curbs following surge in Covid-19 cases in the country.
The administration in Beijing have also restricted access to tourist sites and advised residents not to leave the city unless necessary.
