China was put on notice on Wednesday that if it did not address its air pollution problems before the 2008 Beijing Olympics, it could see games organisers ordering some endurance events to be rescheduled.
The warning from Jacques Rogge, president of the International Olympic Committee, clouded celebrations to mark the final year of the games’ preparations, especially for Beijing organisers who have tried to wave aside pollution worries with assurances of improvement and vague promises of further environmental action.
