Beijing has decided to reopen controversial plans to dam the Nu River in Yunnan province - eight years after Premier Wen Jiabao suspended the plans out of environmental concerns.
The decision was mentioned in a 2011-15 energy-sector blueprint that was released by the State Council late on Wednesday night, sparking criticism about a lack of openness in the decision on the dams.
"Hydropower bases on the Nu River and the upper reaches of the Jinsha and Lancang [Mekong] will be kicked off in an orderly manner," says the document posted on the central government's website.
Some environmentalists were stunned by the plan's revival, which is part of an effort by the government to promote hydroelectricity as a cleaner alternative to coal.
Opponents said the decision marks a long-awaited victory for the country's mighty state-owned power companies and local governments that have been lobbying top leaders to promote the building of mega dams, regardless of the potential safety risks and social consequences.
"This is really shocking," said Li Bo, a director at Friends of Nature, a leading environmental group. "There were signs during the past year that mega dams were staging a comeback after being put on hold for years, but I'm still shocked by the lack of transparency in the decision-making process behind this.
