Students in schools across several Beijing districts buckled down for online classes on Monday after officials called for residents in some of its hardest-hit areas to stay home, as COVID cases in China's capital and nationally ticked higher.

China is fighting numerous COVID-19 flare ups, from Zhengzhou in central Henan province to Chongqing in the southwest and for Sunday reported 26,824 new local cases, nearing April's peaks. It also recorded two deaths in Beijing, up from one on Saturday, which was China's first since late May.

Guangzhou, a southern city of nearly 19 million people that is battling the largest of China's recent outbreaks, ordered a five-day lockdown for its Baiyun district, its most populous. It also suspended dine-in services and shut night clubs and theatres in Tianhe, home to the city's main business district.

Asian share markets and oil prices slipped on Monday as investors fretted about the economic fallout from the intensifying COVID situation in China, with the risk aversion benefiting bonds and the dollar.

The latest wave is testing China's resolve to stick to adjustments it has made to its zero-COVID policy, which calls for cities to be more targeted in their clampdown measures and steer away from catch-all lockdowns and testing that have strangled the economy and frustrated residents.

Several Chinese cities began cutting routine community COVID-19 testing last week, including the northern city of Shijiazhuang, which became the subject of fervent speculation that it could be a test bed for policy relaxation. This sparked worry among some local residents.

But late on Sunday, Shijiazhuang announced it would conduct mass testing in six of its eight districts over the next five days after new daily local cases hit 641. It also encouraged residents to shop online and ordered some schools to suspend in-person teaching.

"They lasted a week," said one popular comment on Weibo on Shijiazhuang's curbs, which was among the most viewed topics on the social media platform.

The capital Beijing reported 962 new infections, up from 621 a day earlier. Its sprawling Chaoyang district, home to 3.5 million people, urged residents to stay home, with school going online. Some schools in Haidian, Dongcheng and Xicheng also halted in-person teaching.

China's recent efforts to make its COVID-19 curbs more targeted have sparked investor hopes of a more significant easing even as China faces its first winter battling the highly transmissible Omicron variant.

Many analysts expect such a shift to begin only in March or April, however, with the government arguing that President Xi Jinping's signature zero-COVID policy saves lives.

Experts warn that full reopening requires a massive vaccination booster effort and a change in messaging in a country where the disease remains widely feared.

Capital Economics wrote in a Monday note that it only expects and exit from zero-COVID in the second half of 2023. "From an epidemiological and political perspective, we do not think the country is ready yet to open up," it said.
