Stringent restrictions usher in blue skies

Major air pollutants in Beijing have been greatly reduced through effective restrictions, municipal environmental authorities said on Tuesday.

They also pledged that tougher action will be taken if there is air pollution in the capital in the days ahead of a grand military parade on Sept 3.

However, it is highly likely that the city will see hazy weather when the parade is held to celebrate victory in the War of Resistance against Japanese Aggression (1937-45).
