The Environmental Protection Ministry announced on Thursday it has begun a six-month campaign targeting the most heavily polluted regions.

The ministry said the campaign, which will begin this month and end in March, will ensure that local governments and enterprises are abiding by regulations implemented on Sept 12 to tackle airborne pollution.

The campaign will primarily involve inspections of regions with the most smog, including the geographic cluster of Beijing, Tianjin and Hebei province, the Yangtze River Delta region, the Pearl River Delta region, and central Liaoning province.
