China must ensure open access to the internet during the Beijing Games, Olympic officials have warned.
Inspectors from the International Olympic Committee (IOC) said China was obliged under its Games contract to provide journalists with web access.
The IOC's Kevan Gosper said there was concern that the web had been blocked during recent unrest in Tibet. He said this could not happen during the Games.
IOC inspectors are on a final visit to Beijing before the August Games begin.
