Er-kang Bio Starch Co Ltd planned to develop 10000 t/y Erkang m-Phenylenediamine Plant Project, in Cambodia. The project covered the construction of an m-Phenylenediamine plant with a capacity of 10000t/y. On May 8, 2020, the Board of Directors of the company reviewed and approved the project proposal for an annual output of 10000 t m-Phenylenediamine. In recent years, China continuously adjusted the structural reforms which included the raw and auxiliary materials industry structure. Er-kang closely followed the "Belt and Road" policy call and carried out a strategic layout in the early stage, moving the raw and auxiliary materials industry chain forward and outward, and extending the layout to the upstream of the pharmaceutical industry-pharmaceutical intermediates, further reducing the cost of raw materials.
