China's National Health Commission said in a statement that 38 of the new confirmed cases were locally transmitted, with 36 of them in Beijing. This is the highest daily infection count for the Chinese capital since authorities started releasing data.
Beijing recorded a jump in new confirmed cases, up from six a day earlier, after it started doing mass-testing at the Xinfadi market in the city's southwestern Fengtai district.
The district has put itself on a "wartime" footing and the capital banned tourism and sports events on Saturday, sparking fears of a new wave of Covid-19.
Beijing uptick in coronavirus cases 'very concerning for Chinese authorities'
Nineteen of the new confirmed cases were so-called imported cases involving travellers from overseas, with 17 of them arriving in Guangdong.
China also reported nine asymptomatic cases, one new suspected case and no new deaths from Covid-19 for June 13.
The total number of Covid-19 cases in mainland China now stands at 83,132, while the death toll remained unchanged at 4,634. China does not count asymptomatic patients, who are infected with the virus but do not display symptoms, as confirmed cases.
Chile's health minister resigns
At least 429,000 people worldwide have died from the respiratory illness, nearly halfway through a year in which countless lives have already been upended as the pandemic ravages the global economy.
The total number of confirmed cases has doubled to 7.7 million in slightly over a month and the disease is now spreading most rapidly in Latin America, where it is threatening healthcare systems and sparking political turmoil.
Brazil now has the second-highest number of virus deaths after the United States, surpassing Britain's toll, and the Chilean health minister resigned on Saturday amid a furore over the country's true number of fatalities.
