 In addition, there are long-standing plans to divert about 200 billion cubic metres of water annually from the upstream sections of six rivers in southwestern China, including the Mekong (Lancang River), the Yarlung Zangbo (called Brahmaputra further downstream) and the Salween (Nu River), to the Yangtze River, the Yellow River and ultimately to the dry areas of northern China through a system of reservoirs, tunnels and natural rivers.The project was considered too immense and costly to be undertaken at the time.The respective rivers are transboundary and any diversion would affect India and Bangladesh in South Asia, and Myanmar, Laos, Thailand, Cambodia and Vietnam in Southeast Asia.
