Americans traveling to China for the Olympic Games in August can expect their hotel rooms there to be monitored, the State Department warned on its website.
"All visitors should be aware that they have no reasonable expectation of privacy in public or private locations," according to the State Department site.
"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," it said.
It added that many hotels and apartment buildings may be poorly built, lack emergency exits, fire extinguishers, carbon monoxide monitors and basic security like locks, alarms, and personnel.
