Can we trust Chinese Covid-19 science? – The Guardian
It started badly, with gag orders, cover-ups and ignored offers of help from overseas, but then the Chinese government seized the narrative. It reined in the burgeoning epidemic of Covid-19 at home, and started exporting its rapidly accumulating scientific knowledge of the disease to the rest of the world. Chinese science has often been marginalised and even mistrusted in the west. But will the pandemic change its standing in the world?
China has moved from student to teacher, says Kate Mason, an anthropologist at Brown University in Rhode Island and author of Infectious Change, an account of how the 2002-3 epidemic of severe acute respiratory syndrome (Sars) in China transformed the way the country managed public health. After Sars, she says, western experts went to China to help it put in place an evidence-based health system that was informed by international research. That system now exists, with its most visible symbol being the Chinese Center for Disease Control and Prevention in Beijing, and this time it has been Chinese experts giving instruction abroad. It has been a good year for China, Mason says.
But China has long held a goal to lead the world in science, and it was already well on its way to achieving it before the pandemic. Five years ago, it didnt appear in the top 10 countries for university rankings; this year, its joint sixth. It is second in the world for output of science and engineering publications, behind the European Union but ahead of the United States, and the impact of Chinese research as measured by the proportion of articles that are highly cited doubled between 2000 and 2016, growing much faster than that of the US and the EU, which increased by around 10% and 30% respectively over the same period.
This turbo-charged performance reflects a long-term policy of rebuilding Chinese research and education in the post-Mao Zedong era, says political scientist and China watcher Anna Ahlers of the Max Planck Institute for the History of Science (MPIWG) in Berlin. Starting from the 1980s, the Chinese government began investing heavily in infrastructure, mass education and the training of a cadre of sophisticated researchers across all Stem disciplines. Then, 20 years ago, its focus shifted outward to achieving global prominence.
Among the initiatives that were devised in this new phase were programmes for recruiting talent from abroad, such as the Thousand Talents Plan, and, domestically, a system of incentives for scientists to publish. These bore fruit, as reflected in the rankings, but they also had negative consequences. The pressure to publish with large cash bonuses paid to scientists for papers appearing in top scientific journals resulted in an increase in academic fraud. Meanwhile, the Thousand Talents Plan has been criticised by the US, Canada and others as a vehicle for espionage and intellectual property theft criticisms that have been lent credence by cases such as that of Harvard nanotechnology expert Charles Lieber, who was arrested earlier this year for allegedly lying about his involvement in the programme.
These tensions reflect a deep ambivalence in the rest of the world with regard to Chinas emergence as a scientific superpower that the pandemic has only accentuated by highlighting that neither viruses nor science can be contained within national borders. On the one hand, there is clear recognition that far less would be understood about Covid-19 and the virus that causes it without Chinese research. On the other, there are well-founded concerns about engaging with an authoritarian, one-party regime with a proven disregard for human rights. Muddying an already complex picture are national interests, and a US-China trade war.
The Thousand Talents Plan distils these tensions. Many wealthy countries have lured talent from abroad in fact, it was the UKs Royal Society that coined the term brain drain to describe the exodus of British talent to the US and Canada in the 1950s and 60s. But questions have been raised about how China uses that talent, and the technology that comes with it.
The main concern is how the Chinese Communist party uses technology for the oppression of its people, says James Jin Kang, a cybersecurity expert at Edith Cowan University in Perth, Australia. He adds that anyone buying technology developed in China should worry about data privacy, and that the pandemic has made it easier for China to recruit scientists who are working from home and hence subjected to less institutional oversight than usual.
Chinas approach to ethics has drawn attention in a different way, now that there is a very real prospect of it being the first country to approve a vaccine against Covid-19, and perhaps also to develop effective treatments for the disease. Chinas very good at speed, says Mason. If the game is speed, theyre going to win. There seems little doubt that the party is pushing its scientists to hand it that propaganda coup, causing some to ask what shortcuts are being taken in the process.
Ethical rules do exist in Chinese academia, Ahlers says, though their enforcement is sometimes lax as illustrated by the case of He Jiankui, the scientist who in 2018 announced that he had edited the genes of human babies for the first time (he was punished later, though, with a prison sentence). There is also greater emphasis on the collective good than in western countries, so that testing an experimental Covid-19 vaccine on military personnel which might be considered unacceptable in Europe or the US is more acceptable there.
Yangyang Cheng, a physicist at Cornell University in New York and sometime critic of the Chinese regime, has written about how loyalty to the party overrides ethical considerations in China with troubling implications for research. But she points out that debates about what is ethical with respect to a vaccine have raged in the US, too, and that westerners need to ask themselves what they are really concerned about when they look east. Are they concerned because it is being done unethically, or because it is being done in China? she asks. I think these two things are often conflated.
Cheng has been struck by the sinophobia on display in the west since the beginning of this pandemic, starting with scrutiny of Chinese eating habits, and ridicule of members of the Chinese diaspora preparing for a pandemic long before their fellow citizens of non-Chinese origin who were more likely to regard Covid-19 as an exclusively Chinese problem. Theres not just a residual but a very active sinophobia in the west, agrees Christos Lynteris, a medical anthropologist at the University of St Andrews.
Thats unfortunate, he says, because it can prevent foreign observers from taking a clear-eyed view of how China is changing and what problems it faces itself. For Harry Yi-Jui Wu, a historian of medicine at the University of Hong Kong, these include the increasing ungovernability of the Chinese people including scientists. Before the 1980s, science was a state-sanctioned, collective enterprise. Afterwards, it became more individualistic and commercially oriented. Scientists took more pride in publishing in high-impact journals and in obtaining patents, Wu says. Though there was still political interference in the choice of research subjects, and over the publication process, the science itself the gathering and analysis of data was relatively free. These are paradoxes that are very common in authoritarian or totalitarian regimes, Lynteris says.
The regime has also made adjustments to its strategy, to keep its ultimate goal of global scientific leadership in sight. Earlier this year, for example, it banned bonuses for publications, encouraging researchers to focus on impact instead, and to publish more in Chinese journals. It has its own fears about foreign espionage. A draft data security law unveiled this year could limit the international sharing of data generated in China. Given the sway China already holds scientifically, as Sonia Qingyang Li of the MPIWG writes in a forthcoming paper, the impact of such changes will likely be felt globally.
The increasing ungovernability of Chinese scientists has also been revealed by this pandemic. As science journalist Debora Mackenzie notes in her book Covid-19, a lab in Shanghai that tried to raise the alarm over the new virus was shut down in early January. But Cheng says the censorship can be traced back to local, not central, authorities. The central government is not directing that censorship directly, she says. But it has created this environment of fear and tension in which local politicians are motivated to suppress any bad news.
The social credit system for monitoring trustworthiness, which has been under construction for five years, could be seen as an instrument of the self-discipline that the party has imposed since the hardline Xi Jinping came to power, to help it maintain control. Its not the only one. Wu is planning to leave Hong Kong soon, feeling that its no longer safe to investigate Chinese history critically there. Such a perception is hardly conducive to Chinas attempts to portray itself as an attractive place to do science, and Ahlers says that Thousand Talents has hit a ceiling in terms of recruiting foreign talent. Besides returning Chinese academics, that talent has mainly consisted of retired professors. China is missing out on the intermediate stratum of active, up-and-coming, mid-career scientists, she says.
How will these tensions be resolved? Within 20 years, Kang predicts, the party will be forced to loosen its grip and give Chinese people more freedom including more scientific freedom. Until then, he says, it will continue to behave aggressively, using technology to increase its power, unless western nations cooperate to prevent it.
The pandemic might provide an opportunity to establish the ground rules of a new relationship. Many Chinese people feel pride in the way their government has handled the crisis, especially when they compare it to the responses of governments in supposedly advanced nations. Many of my friends who are professors say we did well, we set an example why didnt the west want to learn? Is it pride? says economist Dabo Guan of Tsinghua University in Beijing and University College London. And prominent Chinese biomedical scientists have expressed dismay and irritation at persistent western hostility. They see this double standard in how we look at China and what we do ourselves, says Ahlers.
We should welcome Chinas growth in science, says Venki Ramakrishnan, Nobel laureate and president of the Royal Society. For him, that means China should be free to recruit overseas, as western nations have for decades. But at the same time, he adds, we should stand up for what we consider our values, which I believe are universal values theyre not the preserve of the west. They are those values that ensure that science and, indeed, humanity flourish.
