The USA prefers to use space instead for our spying. There are treaties that make it less likely to cause an incident. This is why we have space planes and recon satellites. We also fly over international waters collecting signals intelligence using planes like the Growler. The USA may fly stuff over China, but it will probably be a balloon from some University or NOAA. Also it will probably have an ADS-B transponder or some sort of GPS tracking with notifications to airspace controllers. We don't really need spy balloons. As China is learning, they are more just a way to piss other countries off without much payoff. Especially since the end of the Open Skies Treaty.
