In the opening ceremony of Qingdao Multinationals Summit, the president of OCI group of South Korea, Baikwoosug presented that OCI has invested in the construction of four chemical factories in three Chinese cities and two of their factories are located in Zaozhuang, Shandong province.

Baik Woo Sug said, "In recent years, the pace of China's opening-up has continued to accelerate. China has become the world's largest manufacturing base and consumer market. Not only for the South Korean companies, but also for multinational companies, I believe that the more China opens to the world, the more foreign companies will access to the Chinese market, and the more opportunities Chinese companies will have to cooperate with foreign companies, ultimately realizing the common development of Chinese and global industries."
