British journalist Thomas Hale is the Shanghai correspondent for Financial Times, and he recently published a rare account of what life is like inside one of China's COVID-19 quarantine camps, where he was restricted for 10 days, not because he tested positive for COVID, but because he was tracked through his cell phone as being close to someone else who tested positive for COVID.

The title of the article is I spent 10 days in a secret Chinese Covid detention centre.

The call came from a number I did not recognise.

"You need to quarantine," a man on the other end of the line said in Mandarin. He was calling from the Shanghai Municipal Center for Disease Control and Prevention. "I'll come and get you in about four or five hours."

I dashed out of my hotel to stock up on crucial supplies. Based on advice from colleagues and my previous experience of quarantine in China, these included: tinned tuna, tea, biscuits, three types of vitamin, four varieties of Haribo sweets, Tupperware, a yoga mat, a towel, cleaning equipment, an extension cable, a large number of books, eye drops, a tray, a mug and a coaster with a painting of the countryside surrounding Bolton Abbey in North Yorkshire.

Four to five hours later, I received another phone call. This time it was a woman from the hotel's staff. "You are a close contact," she said. "You can't go outside."

"Am I the only close contact in the hotel?"

I was, she told me and added "the hotel is closed", meaning locked down. I went to the door of my room and opened it. A member of staff was standing there. We both jumped.

You can’t go outside,” she said, mid-jump.

“Will the staff be able to leave?” I asked apologetically.

“It’s OK. I’ve just started my shift,” she replied, smiling.​

What follows is a detailed account of his experience, which is apparently quite rare for a foreigner, and perhaps resulted from a misspelling of his name when his information was entered into their COVID-19 tracking system.

And while being forcibly confined as basically a prisoner, one of the things that apparently surprised Hale was how compliant and accepting the Chinese were to such drastic measures with China’s ZERO Covid policies.

One man told me he estimated that 90 per cent of Chinese people agreed with the government’s approach.

That approach, known as “zero Covid”, is one of maximal suppression of the virus. It employs contact tracing, constant testing, border quarantine and lockdowns in order to stop community transmission of the virus as soon as a case is detected. It is aggressive and could only really exist in the long-run in an autocratic society with the mechanisms for mass surveillance already in place. There is no end in sight to the policy, despite China’s vaccination rate of about 90 per cent.

He documents his being taken away to an island where the quarantine camp was built, and where few foreigners have ever been.

The men in hazmat suits arrived a little later. First, they administered a PCR test with the same rushed weariness of the man who had called me earlier. Then, one escorted me down the deserted hallway. We passed the lifts, which were blocked off and guarded, and took the staff elevator. Outside, the entrance was also cordoned off. A hotel with hundreds of rooms had been frozen for me alone. I was being “taken away”, as this process is commonly referred to in China these days.

In the empty street, a bus was idling. It was small, a vehicle for school trips or large families, maybe. We drove off. “Are we going to another hotel?” I asked one of the dozen or so passengers on board.

“It’s not a hotel,” he said.

“Tian a,” another passenger said. This expression, often translated as “Oh my God”, conveyed more of a “For goodness’ sake” in this case.

The mood in the bus was not fearful so much as detached. The pop music whining out of the radio was occasionally mauled by severe static. Nobody seemed to notice. It is a curious experience, as an adult, to be driven somewhere without having any idea of the destination. Our driver, enmeshed in a hazmat suit, spoke frantically on his phone with some distant authority. After an hour or so, his driving seemed to become more frantic too, and my mind flashed to recent news reports from Guizhou province in which a quarantine transport bus had crashed, killing 27 passengers. I fastened my seatbelt and repositioned my suitcase, which was blocking the aisle.

Eventually, we came to a stop on a small road in the middle of a field. The driver was instructed, over walkie-talkie, to keep going. But this was impossible because there were several full-sized coaches in front of us, and small crowds of people wandered around in the darkness. “I can’t drive,” he barked into his handset and proceeded to get out, lock the bus behind him and wander off into the night.

I wound down my window, just to see if climbing out might be viable. We were far into the countryside now, and it was surprisingly cold. Then a passenger who was also wearing a hazmat suit — the indiscriminate wearing of hazmat suits made it hard to discern who was in charge — leapt into the driver’s seat. He wasn’t trying to escape, just unlock the door. Outside, people smoked and milled around aimlessly.

“Where are you from?” one of the others asked me. His hazmat gear was rolled down around his waist, like a boiler suit. “The UK,” I said, and his eyes widened.

“They brought you here? With a foreign passport?”

The queue of buses slowly disappeared into what looked like a brightly lit gate at the end of the road. Cigarette smoke in the night air cast a silver pall over the fields. There was the sense of some vast structure behind the darkness. The placement of suitcases and bags inside the bus meant we were all in slightly uncomfortable positions, though one person had fallen asleep and was snoring loudly. Another played solitaire on his phone. We waited. None of us — not me, not the other passengers, not our driver — had tested positive for Covid-19.

Around 2am, our driver climbed back on board. The engine revved and the radio burst into life with a crackle. It was our turn. We continued deeper inside China’s quarantine apparatus, the kind of place that finds you, rather than the other way around. It is part of a system scarcely conceived of or understood by the outside world, one defined almost in opposition to it. It is a system that seeks to eliminate rather than cohabit with coronavirus, one in which an unknown number of people are detained. And it is a place foreigners might imagine, but where few have ever been.
