Its financial markets may be even more dangerous than its wildlife markets.

The mighty Chinese juggernaut has been humbled this week, apparently by a species-hopping bat virus. While Chinese authorities struggle to control the epidemic and restart their economy, a world that has grown accustomed to contemplating China’s inexorable rise was reminded that nothing, not even Beijing’s power, can be taken for granted.

We do not know how dangerous the new coronavirus will be. There are signs that Chinese authorities are still trying to conceal the true scale of the problem, but at this point the virus appears to be more contagious but considerably less deadly than the pathogens behind diseases such as Ebola or SARS—though some experts say SARS and coronavirus are about equally contagious.

China’s initial response to the crisis was less than impressive. The Wuhan government was secretive and self-serving; national authorities responded vigorously but, it currently appears, ineffectively. China’s cities and factories are shutting down; the virus continues to spread. We can hope that authorities succeed in containing the epidemic and treating its victims, but the performance to date has shaken confidence in the Chinese Communist Party at home and abroad. Complaints in Beijing about the U.S. refusing entry to noncitizens who recently spent time in China cannot hide the reality that the decisions that allowed the epidemic to spread as far and as fast as it did were all made in Wuhan and Beijing.
