China reported on Saturday (July 31) 55 new coronavirus cases in the mainland for July 30, compared with 64 cases a day earlier, the health authority said.
The National Health Commission said in a statement 30 of the new infections were local cases, compared with 21 the previous day. There were no new deaths.
A majority of the local cases were reported in Jiangsu province, the authority said.
More than 200 infections nationwide have been linked to a cluster in eastern Jiangsu province, where nine cleaners at an international airport in the city of Nanjing tested positive on July 20.
The Nanjing city authorities ordered all tourist attractions and cultural venues not to open on Saturday, prompted by the spike in domestic transmissions.
Hundreds of thousands have already been locked down in Jiangsu province, while Nanjing has tested all 9.2 million residents twice.
The tourist city of Zhangjiajie in Hunan province, where a handful of cases attended a single theatre performance, locked down all 1.5 million residents and shut all tourist attractions on Friday, according to an official notice.
Famed for its striking rock formations, the city is where part of the Avatar blockbuster was filmed.
In Beijing's Changping district, where two locally transmitted cases have been found, 41,000 people in nine housing communities were placed under lockdown on Thursday.
China has previously boasted of its success in snuffing out the pandemic within its borders after imposing the world's first virus lockdown in early last year as Covid-19 seeped out of Wuhan in the centre of the country.
But an outbreak this month driven by the fast-spreading Delta variant has thrown that record into jeopardy.
As of July 30, mainland China had a total of 92,930 confirmed coronavirus cases. China’s death toll from the coronavirus remained unchanged at 4,636.
