In August, there was an unexpected stir in China about a scholarly article. The piece, published in a respected but specialist journal, argued that during the Ming dynasty (1368-1644) and Qing dynasty (1644-1911), China had been a country relatively closed off to the outside world. Most recent scholarship has assumed that this was a bad thing and that greater openness in the modern era had led to China’s rise in global standing and growth. But the article took a contrarian position, suggesting that there were economic and social advantages to the doors being closed in large part. The argument might have stayed in the realms of the academic. But it was then sent out on the social media feed of a thinktank closely linked to the Chinese Communist party (CCP). There was plenty of social media comment, mostly wondering whether the CCP was hinting that today, too, China should think about whether openness was quite such a good idea.
