Your paranoia is really getting to you. China would build the airframe, but all electronics and other goodies would be installed domestically. It would be trivial to find any listening device, and the Chinese aren't stupid enough to try. I don't think letting the Chinese manufacture the presidents helicopters are a good idea, but that is more to inconsistent quality control than some kind of stupid conspiracy.If the president's helicopters are built in China the Chinese will install listening devices and homing beacons. I am not kidding.
