On November 27, 2013, United Nations Commission on International Trade Law (UNCITRAL) Regional Center for Asia and the Pacific (RCAP), in collaboration with the Korea Ministry of Justice, organized a capacity-building event to assist Cambodian government to draft the e-commerce legislation. In the context of the UN legal technical assistance exercise, Prof. Hong Xue, Director of BNU Institute for Internet Policy & Law, and the other two Korean professors, were invited to give lectures to the Cambodian governmental officials from the Ministry of Commerce, Ministry of Justice, Royal Academy of Judicial and academicians on fundamentals of e-commerce law, on the basis of the UNCITRAL texts. Prof. Xue gave the lecture in the morning and received very positive feedback. During the lecture, Prof. Xue primarily analyzed the draft Cambodian E-Commerce Law (version 4) and compared with the UNECC and many other international and national law. The Cambodian delegates warmly welcomed the timely exercise and asked many relevant questions to deepen their understanding on the norms and rules of e-commerce law. The whole event ended with a huge success. The newly established UNCITRAL-BNU Joint Certificate Program is expected to contribute to the legal technical assistance exercise provided by RCAP.
