I first met Xiaogang Peng in the summer of 1992 at Jilin University in Changchun, in the remote north-east of China, where he was a postgraduate student in the department of chemistry. He told me that his dream was to get a place at a top American lab. Now, Xiaogang was evidently smart and hard-working – but so, as far as I could see, were most Chinese science students. I wished him well, but couldn’t help thinking he’d set himself a massive challenge.

Fast forward four years to when, as an editor at Nature, I publish a paper on nanotechnology from world-leading chemists at the University of California at Berkeley. Among them was Xiaogang. That 1996 paper now appears in a 10-volume compendium of the all-time best of Nature papers being published in translation in China.

I watched Xiaogang go on to forge a solid career in the US, as in 2005 he became a tenured professor at the University of Arkansas. But when I recently had reason to get in touch with Xiaogang again, I discovered that he had moved back to China and is now at Zhejiang University in Hangzhou – one of the country’s foremost academic institutions.

For Xiaogang, it seems that America was no longer the only land of opportunity. These days, Chinese scientists stand at least as good a chance of making a global impact on science from within China itself.

The economic rise of China has been accompanied by a waxing of its scientific prowess. In January, the United States National Science Foundation reported that the number of scientific publications from China in 2016 outnumbered those from the US for the first time: 426,000 versus 409,000. Sceptics might say that it’s about quality, not quantity. But the patronising old idea that China, like the rest of east Asia, can imitate but not innovate is certainly false now. In several scientific fields, China is starting to set the pace for others to follow. On my tour of Chinese labs in 1992, only those I saw at the flagship Peking University looked comparable to what you might find at a good university in the west. Today the resources available to China’s top scientists are enviable to many of their western counterparts. Whereas once the best Chinese scientists would pack their bags for greener pastures abroad, today it’s common for Chinese postdoctoral researchers to get experience in a leading lab in the west and then head home where the Chinese government will help them set up a lab that will eclipse their western competitors.
