Context

If you look here, you get the global tally of Covid-19 by country. What you don't get is a more accurate population context. As you can see, China sports a 'Cases per 1M' a fraction of the USofA. But is that meaningful?

We know that the outbreak started in Wuhan (planted by the CIA or not :) ) and Xi ordered the lockdown soon after. Infection across China has not been widespread, the number of confirmed cases outside Hubei has shown a decreasing trend. Unlike for the USofA, since The Orange Shitgibbon let it spread like wildfire. And it is.

A better metric of control is to track the change in number of MSAs at risk for infection. That won't be a good number for the USofA, since new MSAs 'come on-line' with infection frequently (every day?). Likely, all those safe spots in The Orange Shitgibbon's Base are rapidly falling in number. And not a hospital any where.

I don't have the time or inclination to track down all the census data in both countries, but if you use MSA population numbers (and Chinese equivalents) for infected areas, China might not look so much better. But in terms of new MSA infection, it might well.
