What is the relationship between Jinpu Group and Nanjing Chemical Industry Group?

I'm from Gimpo and have nothing to do with Nanhua. There are 7 chemical plants in Jinpu, among which Zhongshan Chemical Titanium White Jinling Plastics was originally a state-owned enterprise, which was acquired by Jinpu after restructuring. Jinpu Rubber is a joint venture with Yangzi Petrochemical, Jinpu Jinhu is a joint venture with Bang Qi, and Jinpu Sha Ying is a joint venture with Mexi. The last new material of Jinpu is the first factory opened by Jinpu's boss himself.
