From the State Department's fact sheet for American athletes traveling to Beijing for the 2008 Olympics: Your hotel room is bugged.
All visitors should be aware that they have no reasonable expectation of privacy in public or private locations. All hotel rooms and offices are considered to be subject to on-site or remote technical monitoring at all times. Hotel rooms, residences and offices may be accessed at any time without the occupant’s consent or knowledge.
