The expected merger between OCI Group and Hanmi Group has been called off after a general meeting of shareholders at Hanmi Science, the holding company of Korea's leading drug firm Hanmi Pharmaceutical, on Thursday. The management conflict within the founding family has also temporarily ended as Lim Jong-yoon and Lim Jong-hoon, the first and second sons of founder Lim Sung-ki, secured enough seats on Hanmi Scien.
