According to the national development and Reform Commission on November 20, the report released by the China Macroeconomic Research Institute shows that in view of the sharp rise in coal prices in the early stage, the relevant departments quickly adopted a series of measures to ensure supply and stabilize prices, and achieved immediate and obvious results. Driven by the sharp decline in coal prices, the prices of steel, aluminum, glass, pulp, PVC, methanol and coal chemical products have also fallen sharply recently, and the rising pressure on the prices of some raw materials has been significantly relieved.
