Guardian just had an article on “Pollution forces cancellation of air show for Chirac”
“Millions of Beijing residents were warned to stay indoors at the weekend as a hazardous smog choked the city, closed highways and forced the cancellation of an air show for the visiting French president, Jacques Chirac.
The haze, which is caused by low-grade petrol used in the city’s rapidly increasing number of cars, was said to be as bad as at any time for several years despite measures to clean the air in the lead-up to the Beijing Olympics. ”
