THE Korea Exchange (KRX) and the Cambodian government will sign an official joint-venture agreement on Cambodia's proposed stock exchange today, KRX project director Inpyo Lee said Sunday. The agreement will be signed by KRX chairman and CEO Lee Jung-hwan and Finance Minister Keat Chhon at the Ministry of Finance. The signing ceremony was originally scheduled for February 19 but was postponed when Lee Jung-hwan injured his back and was unable to travel.
