It is worth remembering, too, that Americans were equally ignorant of China in the 1970s. Many had been drawn to the romantic egalitarianism of Mao and his Cultural Revolution exhortations. Jonathan Mirsky had so wanted to get to China in 1969 he’d tried to swim there. Two days in the country had been enough to make him a lifelong critic of Chinese authoritarianism. Others remained drawn to China but nonetheless questioned aspects of Maoist propaganda. Why, if women held up half the sky, were China’s leadership committees at every level staffed almost wholly by men, they asked? Some of these early visitors also went on influence at home: Susan Shirk would become deputy assistant secretary of state under President Bill Clinton and first visited China as a student in 1971.
China is not yet limiting the number of American students it admits. In any case, the number is very low – 900, down from 15,000 a decade ago. But the hostility with which Chinese students and academics are treated makes it even less likely that Americans will be willing to study in the country, preventing the development of more nuanced and sophisticated understandings of America’s most important competitor, as well as Chinese language skills that are key to comprehending Chinese geopolitical intentions and ambitions.
There are valid reasons to limit China’s access to most advanced American knowledge and technology. In the 1970s, American academics noticed that some techniques studied closely by visiting Chinese scientists – in agricultural mechanisation, for example – had been quickly applied back in China. There was satisfaction, and some trepidation.
By the late 1970s universities and laboratories had put in controls to disrupt what would now be called economic espionage. Researchers were barred from spending weeks studying technology in a single lab and background checks were conducted.
Such protections remain appropriate today, but a ban on Chinese students studying any STEM subject would only push fee-paying Chinese undergraduates to get this comparatively basic training at European universities or at home in China, something that may well please Beijing.
More fundamentally, a wholesale demonisation of Chinese students and academics risks reducing not only the number of Chinese students in the United States but also their regard for American values. Without the chance for direct exposure to the United States, young Chinese people will again have limited means to counter their government’s propaganda about a geopolitical rival: they will be told, as Mao told young people in the 1960s, that the United States is a failing society working to keep China down. Such a belief, if left unchallenged, could be of enormous consequence in the coming decades of Sino–American competition.
