Comac aircraft are barely even functional. They're death traps and which is why they're only sold in China to state-owned airline companies. China has leverage over US companies, but that's not without consequences. China doesn't have leverage over the US though. US would be okay with some US companies losing out in China and using that as a tool to drive it's own companies out of China.
