China reported dozens of new local coronavirus infections on Saturday, a day after the government reaffirmed its commitment to strict measures designed to limit the pandemic’s spread within its borders.

The country’s National Health Commission on Sunday reported 74 new cases for the previous day, of which 50 were locally transmitted. A wave of cases has reached the majority of its 31 provinces, in the broadest outbreak since the early days of the coronavirus last year.

The data was released after officials at a press conference in Beijing said China would continue to adhere to its prevention measures even as other countries in the region abandoned their zero-Covid policies.

Wu Liangyou, an official at the National Health Commission, said China faced a “complex and grave challenge this winter and next spring” in controlling the virus, because the pandemic remained at elevated levels in neighbouring countries and across the world.

In China, which is hosting the Winter Olympics for the first time in February next year, new cases slowed to a trickle in mid-2020 and authorities have reacted swiftly to any prospect of a big outbreak ever since.

The emergence of the highly infectious Delta variant within the country, which hit the eastern city of Nanjing in July, led to dramatic measures designed to limit its spread, including travel restrictions.

There are signs of increasingly harsh constraints in the country, which has reported almost 1,000 new cases since mid-October. Last weekend, tens of thousands of visitors were locked inside Disneyland in Shanghai for mass testing after a case related to the theme park was discovered a day earlier. The government has also warned households to store food in case of emergencies.

China’s efforts to control the pandemic come against the backdrop of a broader economic slowdown, with economists pointing over recent months to the impact of the restrictions on consumer spending, alongside weakness in the property sector and energy shortages.

While gross domestic product in the third quarter fell to its slowest pace of growth in a year, at 4.9 per cent, data on Sunday showed resilience in China’s exports, which also helped drive its rapid recovery from the early stages of the pandemic last year. In dollar terms, exports beat expectations to rise 27 per cent in October year-on-year.

“China’s economy shows [a] similar pattern in October as in earlier months: exports remained strong due to recovering global demand, while domestic activities likely stayed subdued partly driven by the regional Covid outbreaks,” said Zhiwei Zhang, chief economist at Pinpoint Asset Management.
