Hacked Trove of Documents Show China’s “Weaponized System of Censorship”

(p. 1) In the early hours of Feb. 7 [2021], China’s powerful internet censors experienced an unfamiliar and deeply unsettling sensation. They felt they were losing control.

The news was spreading quickly that Li Wenliang, a doctor who had warned about a strange new viral outbreak only to be threatened by the police and accused of peddling rumors, had died of Covid-19. Grief and fury coursed through social media. To people at home and abroad, Dr. Li’s death showed the terrible cost of the Chinese government’s instinct to suppress inconvenient information.

Yet China’s censors decided to double down. Warning of the “unprecedented challenge” Dr. Li’s passing had posed and the “butterfly effect” it may have set off, officials got to work suppressing the inconvenient news and reclaiming the narrative, according to confidential directives sent to local propaganda workers and news outlets.

They ordered news websites not to issue push notifications alerting readers to his death. They told social platforms to gradually remove his name from trending topics pages. And they activated legions of fake online commenters to flood social sites with distracting chatter, stressing the need for discretion: “As commenters fight to guide public opinion, they must conceal their identity, avoid crude patriotism and sarcastic praise, and be sleek and silent in achieving results.”

The orders were among thousands of secret government directives and other documents that were reviewed by The New York(p. 14)Times and ProPublica. They lay bare in extraordinary detail the systems that helped the Chinese authorities shape online opinion during the pandemic.

At a time when digital media is deepening social divides in Western democracies, China is manipulating online discourse to enforce the Communist Party’s consensus. To stage-manage what appeared on the Chinese internet early this year, the authorities issued strict commands on the content and tone of news coverage, directed paid trolls to inundate social media with party-line blather and deployed security forces to muzzle unsanctioned voices.

. . .

The documents include more than 3,200 directives and 1,800 memos and other files from the offices of the country’s internet regulator, the Cyberspace Administration of China, in the eastern city of Hangzhou. They also include internal files and computer code from a Chinese company, Urun Big Data Services, that makes software used by local governments to monitor internet discussion and manage armies of online commenters.

The documents were shared with The Times and ProPublica by a hacker group that calls itself C.C.P. Unmasked, referring to the Chinese Communist Party. The Times and ProPublica independently verified the authenticity of many of the documents, some of which had been obtained separately by China Digital Times, a website that tracks Chinese internet controls.

. . .

“China has a politically weaponized system of censorship; it is refined, organized, coordinated and supported by the state’s resources,” said Xiao Qiang, a research scientist at the School of Information at the University of California, Berkeley, and the founder of China Digital Times. “It’s not just for deleting something. They also have a powerful apparatus to construct a narrative and aim it at any target with huge scale.”

“This is a huge thing,” he added. “No other country has that.”

WHO Team Unable to Conduct a Thorough and Impartial Study of Wuhan Origin of Covid-19

(p. A1) . . . , as the WHO-led team finalizes its full report on the Wuhan mission, a Wall Street Journal investigation has uncovered fresh details about the team’s formation and constraints that reveal how little power it had to conduct a thorough, impartial examination—and call into question the clarity its findings appeared to provide.

. . .

(p. A10) The WHO asked the U.S. to recommend government experts for the team, but it didn’t contact the three that Washington put forward, according to current and former U.S. officials.

. . .

On Jan. 23, 2020, a WHO emergency committee recommended that a WHO-led group of scientists should “review and support efforts to investigate the animal source of the outbreak.”

. . .

Tedros Adhanom Ghebreyesus, the WHO’s director-general, discussed the matter with President Xi Jinping in a January 28 meeting. The next month, a WHO-led team, including two U.S. government experts, visited China.

Local officials appeared committed to a search and described work they had under way, according to people on that trip. But no studies emerged over the following weeks.

. . .

The team included leading specialists in animal health, epidemiology and virology, and government experts from Germany, Russia and Japan.

It included one scientist from the U.S.: Peter Daszak, a zoologist and president of EcoHealth Alliance, a New York-based nonprofit.

Dr. Daszak had experience hunting for the origins of emerging human viruses in animals, including 16 years working with researchers in China. He was on a team that pinpointed bats as the source of the coronavirus behind SARS.

Some U.S. officials and scientists were concerned some of his nonprofit’s work in China posed a conflict of interest. EcoHealth had in past years provided funding to the Wuhan Institute of Virology as part of a grant from the U.S. National Institutes of Health. The WIV is at the center of assertions by the Trump administration that the pandemic virus could have come from a lab, and Dr. Daszak had publicly dismissed the possibility.

In applying for a spot on the team, Dr. Daszak said, he described his expertise and provided a conflict-of-interest statement to the WHO including his work with the WIV.

. . .

On Jan. 28 [2021], a year to the day from the WHO director-general’s meeting with President Xi, they were cleared to begin field visits and face-to-face meetings with Chinese counterparts. For the remainder of the trip, they were restricted mainly to one part of a hotel due to more quarantine rules and forced to eat separately from Chinese counterparts—preventing the kind of informal conversations team members said were often the most fruitful in such efforts. Their contact with anyone outside the team was limited.

It soon became evident to foreign officials and scientists tracking the mission that the team’s itinerary was partly designed to bolster China’s official narrative that the government moved swiftly to control the virus. The team’s first visit was to a hospital where they met a doctor Beijing feted as the first to raise alarms through official channels about an outbreak of unknown pneumonia. The next day, after another hospital visit, the team went to an exhibition commemorating Chinese authorities’ early “decisive victory in the battle” against the virus, paying tribute to President Xi’s leadership.

. . .

Team members said it became clear to them that Chinese authorities would mostly present only their data analysis, not the raw numbers. And they hadn’t completed some short-term tasks the team had hoped for, including detailed studies of blood samples from before December 2019 and compiling a definitive list of animals sold at the Huanan market.

Among the 30 to 60 Chinese participants were nonscientists, including foreign-ministry officials, team members said. China’s team leader has said his team included 17 experts. The Chinese foreign ministry said none of its officials were in the expert group.

A heated exchange during one meeting touched on the pivotal question of how widely the virus spread around Wuhan before the first confirmed case, who Chinese officials say got sick on Dec. 8, 2019.

. . .

After leaving Wuhan, some international team members qualified their verdict on the laboratory. They lacked the authority, expertise or access to conduct a full examination of the WIV or any other research facility, several said publicly or to the Journal.

Several said that they hadn’t been able to see the raw data or original safety, personnel, experiment and animal-breeding logs—which many other scientists say are necessary elements of a full investigation.

“It’s just a great coup by China,” said Daniel Lucey, a clinical professor of medicine at the Geisel School of Medicine at Dartmouth who also teaches at Georgetown University.

A thorough investigation of a potential lab leak would require experts with forensic skills similar to those who do weapons or biowarfare inspections, scientists including Dr. Dwyer said.

“We didn’t see the actual data there,” Dr. Dwyer said. “It would be nice to have seen that, particularly around the testing of their staff and so on. But that didn’t come through. They could still provide that.”

Only Very Few of Those Vaccinated Get Covid-19, and When They Do, Symptoms Are Mild or Absent

(p. A8) Nearly 83 million Americans have received at least one dose of a Covid vaccine, and it’s unclear just how many of them will have a “breakthrough” infection, though two new reports suggest the number is very small.

One study found that just four out of 8,121 fully vaccinated employees at the University of Texas Southwestern Medical Center in Dallas became infected. The other found that only seven out of 14,990 workers at UC San Diego Health and the David Geffen School of Medicine at the University of California, Los Angeles tested positive two or more weeks after receiving a second dose of either the Pfizer-BioNTech or Moderna vaccines. Both reports, published on Tuesday [March 23, 2021] in the New England Journal of Medicine, show how well the vaccines work in the real world, and during a period of intense transmission.

. . .

Only some of the virus-positive health workers in the California study showed symptoms, . . ., and they tended to be mild, suggesting that the vaccines were protective. That echoes data from the vaccine trials indicating that breakthrough infections were mild and did not require hospitalizations. Some people had no symptoms at all, and were discovered only through testing in studies or as part of their medical care.

Successful Chinese Entrepreneur Stands Trial for Defending Free Speech

(p. A10) Like many entrepreneurs in China, Geng Xiaonan found a space in which to make a small fortune — in her case, publishing books on cooking, health and lifestyle.

But unlike many Chinese entrepreneurs, she mixed with critics of the party, organizing dinners and salons that brought together liberal intellectuals, retired officials and longtime dissenters.

Now, Ms. Geng is set to stand trial in Beijing on Tuesday [Feb. 9, 2021] and may spend years in prison for her support for those at odds with China’s deepening authoritarianism, her supporters say. She and her husband, Qin Zhen, have been charged with illegal business activities related to their publishing company. Friends and sympathetic legal experts maintain that her real offense in the eyes of the government was straying from business into sympathizing with critics of Communist Party power.

Ms. Geng, 46, came under growing surveillance last year after she leapt to the defense of Xu Zhangrun, a law professor in Beijing who was suspended after publishing essays scathingly critical of the party and its top leader, Xi Jinping.

“This is simply political persecution,” said Cai Xia, a former professor at the Central Party School in Beijing, who said she had been friends with Ms. Geng for about eight years. Ms. Cai has moved to the United States, where she has denounced the Chinese Communist Party’s tightening of political controls.

“It’s a selective system of enforcement,” Ms. Cai added. “They can make up whatever they want when they want to slap a crime on you.”

Ms. Geng is the latest among a handful of Chinese entrepreneurs detained or imprisoned since last year as the party draws a harder line on businesspeople it deems challengers of Beijing’s rule.

Many Chinese Have “Desperate Need” to “Hear Different View Points”

(p. A1) One by one, the chatroom participants took the digital microphone as thousands quietly listened in.

A Chinese man said he did not know whether to believe the widespread reports of concentration camps for Muslims in the far western region of Xinjiang. Then a Uighur woman spoke up, calmly explaining that she was certain of the camps’ existence because her relatives had been among those interned. A man from Taiwan chimed in to urge understanding on all sides, while another from Hong Kong praised the woman for her courage in coming forward.

It was a rare moment of cross-border dialogue with people on the mainland of China, who are usually separated from the rest of the online world by the Great Firewall. For a short time, they found an open forum on the social media app, Clubhouse, to discuss con-(p. A10)tentious topics, free from the usual constraints of the country’s tightly controlled internet.

By Monday [Feb. 8, 2021] evening, the inevitable happened: The Chinese censors moved in. Many mainland users reported receiving error messages when they tried to use the platform. Some said they could only access the app by tunneling through the digital border using a VPN, or virtual private network. Within hours, more than a thousand users had tuned in to hear a discussion about the ban in a chatroom titled “Walled off, so now what?” Searches for “Clubhouse” on the popular Chinese social media platform Weibo were blocked.

To many users in mainland China, it was a brief window into an unfettered social media. Under China’s leader, Xi Jinping, the government has been ramping up its efforts to assert near-total digital control over what its citizens read and say online.

. . .

“Clubhouse is exactly what Chinese censors don’t want to see in online communication — a massive, freewheeling conversation in which people are talking openly,” said Xiao Qiang, founder of China Digital Times, a website that tracks Chinese internet controls. “It’s also a reminder that when there is an opportunity, many Chinese have a desperate need to talk to each other and to hear different view points.”

Chinese People Yearn for Freedom of Speech

(p. B1) For years, the Chinese government has prevented its 1.4 billion people from speaking freely online. A digital wall separated them from the rest of the world.

Then, for a precious few days, that wall was breached.

Clubhouse, a new social media app that emerged faster than the censors could block it, became a place for Mandarin Chinese speakers from the mainland and anywhere else to speak their minds. They had a lot to say.

. . .

The Chinese government blocked the app Monday [Feb. 8, 2021] afternoon. I knew it was coming, and yet I still didn’t expect to feel so dismayed.

For that brief moment, people in China proved that they are as creative and well spoken as (p. B6) people who enjoy the freedom to express themselves. They lined up, sometimes for hours, to wait for their turns to speak. They argued for the rights of the government loyalists to speak despite their disagreements. They held many honest, sincere conversations, sometimes with tears and sometimes with laughter.

Those conversations helped illuminate why the Chinese government blocks free speech online in the first place. Those free-flowing exchanges threaten to debunk the caricatures that the state-controlled media often foists upon the Chinese people. The state media dismisses people like the Tiananmen protesters, pro-democracy advocates in Hong Kong or those in Taiwan who want the island to take a different path from the mainland.

Likewise, mainlanders got a chance to prove that they aren’t brainwashed drones. People who had been demonized got a chance to speak out and be humanized.

Over the past two decades, Beijing has developed the most sophisticated online censorship system in the world. Big online platforms like Google, Facebook, Twitter and YouTube were blocked long ago. Under Xi Jinping’s leadership, a growing number of topics have become off limits on the Chinese internet. Clubhouse gave mainland Chinese users a chance to flock to chatrooms focused on those taboos.

. . .

Several chatrooms were devoted to the bloody crackdown in Tiananmen Square, a heavily censored topic on the Chinese internet. Cai Chongguo, a student leader during the protests, talked for about four hours, sharing his stories and answering questions from thousands of people.

. . .

Even during the freewheeling conversation, censorship was on the minds of many. On Monday afternoon, one room that reached Clubhouse’s maximum of 5,000 users featured speakers sharing their concerns over whether they would be questioned by the authorities for speaking out on the app.

. . .

A few hours later, mainland users began to report that the app had been blocked. Several rooms were set up immediately for people to chat it over. I joined a room for people to mourn the blocking.

The title of the room featured three candle emoticons. People lined up to share their most memorable experience. A few speakers cried.

. . .

Ms. Sun, who lives in Germany, had never talked about such politically sensitive topics with strangers. Then, on Saturday, she had waited more than two hours to speak in a chatroom about those very topics with thousands of people from mainland China, Taiwan, Hong Kong and other parts of the world.

Someday, she said in an interview, Chinese people would be able to talk freely. Many Eastern Germans didn’t expect the Berlin Wall to fall in 1989, she added, but it happened.

“Nobody can predict the future,” Ms. Sun said. “We should believe in humanity and humanity’s yearning for freedom.”

Black Cuban Dissident Rapper: “Donald Trump 2020! That’s My President”

(p. A12) HAVANA — In another era, the detention of a young Cuban dissident may have gone completely unnoticed. But when the rapper Denis Solís was arrested by the police, he did something that has only recently become possible on the island: He filmed the encounter on his cellphone and streamed it live on Facebook.

The stream last month prompted his friends in an artist collective to go on a hunger strike, which the police broke up after a week, arresting members of the group. But their detentions were also caught on cellphone videos and shared widely over social media, leading hundreds of artists and intellectuals to stage a demonstration outside the Culture Ministry the next day.

This swift mobilization of protesters was a rare instance of Cubans openly confronting their government — and a stark example of how having widespread access to the internet through cellphones is testing the power balance between the communist regime and its citizens.

. . .

In a country hammered by U.S. sanctions, the politics of some in the group have raised eyebrows. Mr. Solís is a die-hard Trump supporter: In the video he posted of his arrest, he screamed: “Donald Trump 2020! That’s my president.”

Even Alibaba Entrepreneur Jack Ma Cannot Speak His Mind in Communist China

(p. A1) Chinese President Xi Jinping personally made the decision to halt the initial public offering of Ant Group, which would have been the world’s biggest, after controlling shareholder Jack Ma infuriated government leaders, according to Chinese officials with knowledge of the matter.

. . .

In a speech on Oct. 24 [2020], days before the financial-technology giant was set to go public, Mr. Ma cited Mr. Xi’s words in what top government officials saw as an effort to burnish his own image and tarnish that of regulators, these people said.

At the event in Shanghai, Mr. Ma, the country’s richest man, quoted Mr. Xi saying, “Success does not have to come from me.” As a result, the tech executive said, he wanted to help solve China’s financial problems through innovation. Mr. Ma bluntly criticized the government’s increasingly tight financial regulation for holding back technology development, part of a long-running battle between Ant and its overseers.

. . .

During his 21-minute speech, he criticized Beijing’s campaign to control financial risks. “There is no systemic risk in China’s financial system,” he said. “Chinese finance has no system.”

He also took aim at the regulators, saying they “have only focused on risks and overlooked development.” He accused big Chinese banks of harboring a “pawnshop mentality.” That, Mr. Ma said, has “hurt a lot of entrepreneurs.”

His remarks went viral on Chinese social media, where some users applauded Mr. Ma for daring to speak out. In Beijing, though, senior officials were angry, and officials long calling for tighter financial regulation spoke up.

After Mr. Xi decided that Ant’s IPO needed to be halted, financial regulators led by Mr. Liu, the leader’s economic czar, convened on Oct. 31 and mapped out an action plan to take Mr. Ma to task, according to the government officials familiar with the decision-making.

How “Single-Payer” Socialized Medicine Works for American Indians

(p. A1) EAGLE BUTTE, S.D.—Kate Miner walked into the Indian Health Service hospital, seeking help for a cough that wouldn’t quit.

An X-ray taken of Ms. Miner’s lungs that day, Oct. 19, 2016, found signs of cancer.

What exactly the IHS doctor said to Ms. Miner about her exam remains in dispute. Notations in her medical file indicate the doctor told her to come back for a lung scan the next day. Her family says they never were given such instructions and weren’t told of the two masses the X-ray revealed.

What is clear is that no further tests were done. And no IHS provider followed up when Ms. Miner returned twice more to the hospital, the only one on the Cheyenne River Reservation, over the next six months, medical records show.

Finally, on May 7, 2017, as the 67-year-old Ms. Miner lay crumpled on a hospital cot, the right side of her body shaking, a physician assistant ordered a CT scan, after her family insisted, according to the records and family members.

“You have two very large masses in your right lung. It’s probably a malignancy,” Ms. Miner’s daughter Kali Tree Top recalled the physician assistant saying.

Ms. Miner reached for her daughter’s hand and started to cry.

Ms. Miner’s encounters with the IHS, and her family’s repeated efforts to get her help there, illustrate how the federal agency can fail the patients who need it most.

“Run With the Herd or Be Crushed by It”

The author of the passages quoted below writes poetry and novels in Havana.

(p. 7) Throughout my life, I’ve seen how powerless parents are in matters regarding their own children. Parents have no say over how their children should be raised, whether they will be conscripted or sent away to school in rural areas, and what dangers could befall them being so far from home and such a young age. They have no say over their children’s manners, religious teachings and political ideologies. There are only two choices: Run with the herd or be crushed by it.

As a teenager in the 1980s, I was taught in a “scientific communism” class that family was the heart of society. But from what I could see, that was no longer the case; organizations with mass followings like the Young Communist League had taken its place.

. . .

I was born and raised in a system that exerts control under the guise of paternalism — a system that caresses you as it beats you, that teaches you but also inhibits you, enlightens you and censures you. We are hostages to a government that behaves like an abusive, old-fashioned and sexist father, from whom we must seek consent and forgiveness.

Wasteful Administrative Health Care Costs

The study quoted from below suggests that the main cure for wasteful administrative costs is a “single payer” system, which is a politically correct euphemism for socialized medicine. I suggest that a better cure would be to eliminate the government middle-man, and make the patient be the payer. The patient as payer would seek and buy low-cost cures or therapies, which would shift efforts at healthcare innovation toward lower cost innovations. As has been suggested for education, vouchers could provide poor patients with the means to pay for basic care.

(p. B4) Even a divided America can agree on this goal: a health system that is cheaper but doesn’t sacrifice quality. In other words, just get rid of the waste.
A new study, published Monday [October 7, 2020] in JAMA, finds that roughly 20 percent to 25 percent of American health care spending is wasteful. It’s a startling number but not a new finding. What is surprising is how little we know about how to prevent it.

. . .

Teresa Rogstad of Humana and Natasha Parekh, a physician with the University of Pittsburgh, were co-authors of the study, which combed through 54 studies and reports published since 2012 that estimated the waste or savings from changes in practice and policy.

. . .

The estimated waste is at least $760 billion per year. That’s comparable to government spending on Medicare and exceeds national military spending, as well as total primary and secondary education spending.

. . .

The largest source of waste, according to the study, is administrative costs, totaling $266 billion a year. This includes time and resources devoted to billing and reporting to insurers and public programs. Despite this high cost, the authors found no studies that evaluate approaches to reducing it.
