Project Background
Yueyang Forest & Paper Co., Ltd. is a subsidiary of China Paper Investment Co., Ltd. under China Chengtong Holdings Group Co., Ltd. China Chengtong is a large enterprise group supervised by the State-owned Assets Supervision and Administration Commission of the State Council. It is one of the first batch of pilot enterprises for the construction of a standardized board of directors and asset management by the State-owned Assets Supervision and Administration Commission of the State Council, and it is also the only central enterprise determined by the State-owned Assets Supervision and Administration Commission of the State Council with "forest pulp and paper" as its main business.
