Authorities cited an improved situation in Singapore, where many people are fully vaccinated and have also caught the virus. Residents are urged to continue wearing masks at crowded places or if they feel ill.

But part of Tao’s anxiety stems from the stark differences in the pandemic strategies adopted by Singapore and his native China, where some of his relatives and friends still live.

Unlike Singapore, whose policies revolve around living with the virus, China is one of few jurisdictions clinging to a zero-Covid strategy, which means it has continued to keep its borders largely shut and conduct strict lockdowns and quarantines.

Chinese authorities on Monday shut down Shenzhen’s Huaqiangbei district, home to the world’s largest electronics wholesale market, to contain a fresh outbreak.

“If something unfortunate happens to my family, I think I might not be so supportive of the Singapore government’s open-door policy,” Tao said. “I fear the decision to ease restrictions has come too early.”

Like Tao, some Chinese immigrants in Singapore remain apprehensive of the new rules. Many have taken to social media, including Chinese microblogging site Weibo, to criticise the move, suggesting the Singapore government has opted for a rapid reopening just to keep its economy afloat.

“This is a government that sacrifices its people’s health for money,” one said. Another comment read: “Singapore has shot itself in the foot again.”

But others lauded the development, saying it was hard to imagine when their friends and loved ones in China could roam the streets without a mask.

One user said: “Come on China! Even though you still have to wear N95 masks, you’ll be as successful as Singapore one day.”

Alfred Wu, an associate professor at the National University of Singapore, said it was not new that Chinese nationals living abroad had been angered by domestic policies, particularly if they were new immigrants.

He noted that some quarters had attempted to push the Singapore government to impose harsher measures such as mass testing of residents in the early stages of the pandemic, an approach that some countries, including China, had adopted.

This, he suggested, could be due to the immigrants’ constant use of Chinese social media platforms containing information disseminated by Beijing.

“They are very much under China’s influence especially when it comes to Covid-19 measures,” Wu said. “They think China’s policy is always right.”

While it would be hard to wire them into thinking from Singapore’s perspective, Wu said their mindsets would gradually change once the policies proved effective.

Singapore made wearing masks outdoors optional in March this year, nearly two years after a blanket mask mandate was imposed in April 2020.

A survey of 1,046 people, conducted on August 25-26 by UK pollster YouGov’s Omnibus online research service, found that nearly 48 per cent of Singapore residents would remain masked in shopping centres after Monday’s rule change.

And 39 per cent said they would remain masked during indoor events or festivals, while 37 per cent said they would do so in places of worship.
