China may have a 160 cities with a million+ people, but, do all of these cities have the infrastructure and opportunities that are the same as or come close to Shanghai, Beijing, Shenzen? IMO, this is a case where quantity alone is a poor metric.
This is a difficult question to accurately answer because the only source of this information is an unreliable one (the Chinese regime). We can, however, assume via observation of how efficient and diverse their manufacturing is, which leads to some baseline assumption they all have above average infrastructure, housing, and other services, in addition to affording salaries to those millions of people that does not result in unmanageable civil unrest. Plenty of experts believe China's infrastructure is ahead of the US at this point. They build 100 miles of high speed rail for the same cost we build 1 mile of tunnel, or 10 miles of toll lane that 90% of commuters won't use.
There are other educated assumptions we can make based on the rapid response to the Wuhan outbreak and the surrounding cities, but in my opinion, based on inference from what we can observe from the outside, the answer is firmly yes.
