SHANGHAI, Nov 13 (SMM) – Shanxi, major coal-producing hub in north China, has ordered its local environmental authorities to drop blanket production cuts in the fight against air pollution this winter.

In a notice earlier this month, the smog-prone province required city authorities to implement winter production curbs on a case-by-case basis. Companies that meet certain environmental standards will be exempt from production restrictions.

The winter production curbs will target main polluting sources including steel, nonferrous, coke, chemicals, building materials and casting sectors.
