New rules to keep skies blue in capital

Celebrating the constant blue skies this winter, Beijing will move forward with a new phase of its environmental campaign of mixed controls on air pollution, focusing on vehicles with high exhaust levels, the acting mayor said on Wednesday.

Beijing will make every effort to maintain blue skies this year and will unveil the new action plan based on the updated analysis of pollutants, the acting mayor, Chen Jining, said.

"Vehicles with high exhaust emissions will be the major target. The current area that allows limited emissions will be expanded to cover the whole city in 2018," he said at the opening ceremony of the first session of the 15th Beijing Municipal People's Congress on Wednesday.
