State-owned enterprises refer to enterprises whose actual controllers are the State Council or local people's governments (including enterprises at the same level supervised by central and local state-owned assets supervision and administration institutions and enterprises whose investments are formed step by step).
Zhongtai Chemical is actually controlled by the State-owned Assets Supervision and Administration Commission of the People's Government of Xinjiang Uygur Autonomous Region, which means that Zhongtai Chemical is a local state-owned enterprise. Once restructured into a joint-stock system, it is now a large chlor-alkali chemical enterprise controlled by Xinjiang Zhongtai (Group) Co., Ltd.
