Zhao Yingmin, vice-minister of ecology and environment, told reporters that the two provinces have been chosen as a key target in the country's anti-smog efforts over the 2018-2020 period, with coal dependence at 90 percent and total emissions second only to the Beijing-Tianjin Hebei region.
After forcing industrial-scale coal users like power plants and steel mills to install technologies designed to curb emissions, China has been shifting focus towards what it calls "scattered" pollution sources, including backstreet workshops.
