In September 1978 the Group became the Department of International Law of the CASS Law Institute. In October 2002, the Center for International Law Studies was officially established on the basis of the Department of International Law and Professor Xia Yong was appointed the director of the Center. In September 2009, with the approval of State Commission Office for Public Sector Reform, the Center was renamed the Institute of International Law and Professor Chen Zexian was appointed the first Director of the Institute.
