“The Nobel Prize is the holy grail for China, and it is still quite elusive for Chinese indigenous scientists to be awarded this prestigious recognition,” said Chengxin Pan, an associate professor of international relations at Australia’s Deakin University. “You could say China has a Nobel Prize complex.”

Becoming a leader in the sciences was more than just an issue of driving economic expansion through technology and innovation, it was a matter of national preservation with deep roots in Chinese history, Pan said.

“China sees the lack of power, lack of scientific achievements and modern technology as largely responsible for the backwardness and humiliation it suffered during much of the 19th century and early 20th century,” he said.

“They need to make up for lagging behind by engaging with the top leading scientists in the world, wherever they are from.”

To that end, celebrated theoretical physicists, organic chemists, neuroscientists and biologists joined Chinese academics and youth scientists for the conference organised by the Shanghai city government and an association of top global scientists known as the World Laureates Association.

Among them were 2019 Nobel Prize for physics laureates Michel Mayor and Didier Queloz, as well as winners of other top prizes including the Wolf Prize, Lasker Award, and Fields Medal for mathematics. Discussions included the latest breakthroughs in disease prevention and drug development, sustainability and new energy, aerospace and black holes, as well as what drives their scientific curiosity.

The event, which culminated with the announcement of an international joint research laboratory for the world’s top scientists, to be established in Shanghai, was lauded by President Xi Jinping in an open letter to the attendees.

“China attaches great importance to the development of the frontier fields of science and technology,” Xi said, stressing China’s willingness to “work with all countries of the world” to “address the challenges of our age”.

The high calibre meeting was a rare opportunity for China to broadcast its message of commitment to scientific advancement, at a time when the reputation of its universities, academics and hi-tech companies have been taking a broad hit as part of a blowback from the US-China trade and tech wars, as well as suspicion among Western countries of China’s geopolitical aims.

In the past year, a number of major global Chinese tech companies, including Huawei and Hikvision, have been blacklisted in the US, while US tech giants like Google and Apple noticeably skipped out on China’s annual state-run World Internet Conference last month. Academic ties between Chinese and Western universities have also been called into question over suspicions of espionage, fraud, and intellectual property theft.

“China is saying we are still open for business and, at this juncture, we more warmly welcome foreign scientists and collaboration between countries in science and technology,” said Zhu Tian, an economics professor at the Chinese Europe International Business School in Shanghai.

The past decade has seen China advance rapidly in the sciences. A surge in government funding, along with successive top level strategies to build up science and tech – including the Made in China 2025 innovation blueprint – and a significant uptick in international collaborations, have propelled the nation on to the global scientific stage.

Recent developments, like the first successful landing of a probe on the far side of the moon earlier this year, the dominance of the 5G network technology created by China’s Huawei, and the opening of the world’s largest radio telescope in Guizhou in 2017, have also raised the country’s profile in emerging tech and science.

But, so far, China’s rising visibility as a scientific powerhouse has been largely driven by scale. A June report by the journal Nature found researchers affiliated with the Chinese Academy of Sciences contributed the greatest number of “high-quality natural sciences research” to international journals compared with their peers at other institutions, while last month the journal found the top four “fastest rising” new universities for research output were all from mainland China.

“To some in the outside world, China is already a powerhouse in innovation … but in terms of the quality of innovations or scientific research, China still lags behind developed countries like the US, UK or Switzerland,” Zhu said.

Despite “making the fastest progress among all countries”, and significant leaps as a developing nation, “China is not at the frontier of technology or science yet,” he said, which is why international engagement, like the recent summit, is key to China’s growth.

“In order to catch up you have to know what is the frontier, you have to learn from those who are at the frontier.”

Tu was the People's Republic of China's first Nobel Prize winner in the sciences and the country’s first woman to win the prize in any category.

China has worked hard to reverse the damage of brain drain, for example with its flagship “Thousand Talents” programme, a high-profile, state-backed recruitment drive set up in 2008 to attract overseas Chinese students and academics back to China with generous funding.

But reaching the frontiers of science, and making Nobel-worthy advancements, will also require China to do some reshuffling of its domestic priorities, which have been heavy on producing innovations in applied sciences and tech, but lighter on the basics – like physics, chemistry, and biology – whose mysteries are probed by the leading labs around the developed world.

“China in the past has been known as a place for incremental innovation, and not the place where really radical innovation and big breakthroughs have come from, but they don’t want to be tinkering at the margins, they want to be a major innovation powerhouse,” said Andrew Kennedy, an associate professor in the policy and governance programme at the Australian National University.

To change this, China has begun to raise investment in basic sciences, Kennedy said, pointing to National Bureau of Statistics figures which indicate an average spending increase of more than 20 per cent each year between 1995 to 2016. Even so, spending at the end of that period – some US$11.9 billion at market rates – still lagged well below the figure cited for the US in 2015, which rang up US$83.5 billion, he said.

The gathering of science laureates itself was further indication of that shift to place more emphasis on basic sciences, the kinds of disciplines the laureates lead, and could be a major boost to that agenda, according to Naubahar Sharif, associate professor of social science and public policy at Hong Kong University of Science and Technology.

“This [event] is a rocket-propelled, massive injection of scientific power into one place, and China has ambitions to gear up their own scientists to this level,” Sharif said, “and I’m sure the local Chinese scientists have been prepped to take advantage of it.”

While China has work to do in pushing back on criticism of questionable practices in intellectual property transfer, or the extent to which they share their own advances with others, collaboration with leading scientists is a crucial part of China’s “long-haul” vision in the sciences, Sharif said.

“If you rub shoulders with the most prestigious scientists of your era, your local scientists will learn something, and there’s going to be knowledge exchange and making linkages and a start to partnerships,” he said.

“This is the way that getting to that frontier can be achieved.”
