The unrest was triggered by a fire in a high-rise block in the western Xinjiang region that killed 10 people last week. Many Chinese believe long-running Covid restrictions in the city contributed to the deaths, although the authorities deny this.

It led to days of widespread protests across various cities, which have since ebbed amid heavy a heavy police presence.

Restrictions in major cities like Guangzhou were abruptly lifted on Wednesday, hours after the city saw violent protests that resulted in clashes between police and protesters.

A community in the capital Beijing also allowed Covid cases with mild symptoms to isolate at home, according to a Reuters report - a far cry from protocols earlier this year which saw entire buildings and communities locked down, sometimes as a result of just one positive case.

Other major cities like Shanghai and Chongqing also saw some rules relaxed.

It comes as one of China's most senior pandemic officials, vice-premier Sun Chunlan, said the virus' ability to cause disease was weakening.

"The country is facing a new situation and new tasks in epidemic prevention and control as the pathogenicity of the Omicron virus weakens, more people are vaccinated and experience in containing the virus is accumulated," she said, according to a Reuters report.

This comes in stark contrast to an earlier message from authorities that the country needed to maintain a strict zero-Covid policy.

Former state media editor Hu Xijin, who now offers pro-Communist Party commentary on Twitter, insisted the moves showed China was now "speeding up to cast aside large-scale lockdowns".

Following the lifting of lockdown measures in many parts of Guangzhou, Lijin Hong, an associate professor at Sun Yat-sen University, said it would "take a while for the city to recover. Yet is is awesome to see Guangzhou city again."

China has in recent days recorded its highest number of daily Covid cases since the pandemic began - with more than 36,000 cases recorded on Wednesday.

However, the numbers are still tiny for a country of 1.4 billion people and officially just over 5,200 have died since the pandemic began.

That equates to three Covid deaths in every million in China, compared with 3,000 per million in the US and 2,400 per million in the UK, although direct comparisons between countries are difficult.
