"There is a history of important Chinese personnel being kidnapped by e.g. the US when abroad" No there isn't. China revoked their passport to keep them prison

"There is a history of important Chinese personnel being kidnapped by e.g. the US when abroad" No there isn't. China revoked their passport to keep them prisoners not to keep them safe. "On a good faith basis, one would think China banning people from leaving is a good thing" Why would anyone think imprisoning someone like this is a good thing?
