This may be a stupid question, but wouldn't US have anything to say about something like this? After all, how would this benefit US based airlines?</font>
Fair trade as far as 5th freedom ("beyond") rights are concerned.
If U.S. airlines can fly to HKG, pick up passengers and fly onward to a foreign destination, CX or any other H.K. airline flying to the U.S.
should be able to do the same.
AFAIK, there aren't too many, if any, passenger 5th freedom rights exercised by U.S. airlines. PA and UA periodically operated HKG-SIN. I think HKG-BKK was operated too.
