THE Ministry of Industry, Mines and Energy signed a memorandum of understanding last week with a Vietnamese state-owned corporation to complete a feasibility study into a potential 980-megawatt hydroelectricity dam in Stung Treng province, Ministry Deputy Director General Victor Zona said Sunday. The study, to be conducted by Vietnam Urban and Industrial Zone Development Investment Corporation would last two years. Eventually a green light would be required from the Ministry of Industry, the Ministry of the Environment and the Mekong River Commission, he said. “If one of these three institutions opposes the project, it will not go ahead.”
