From Reuters:

Chinese plans to turn an untamed river into a hydro-electric hub have sparked a war of words about national priorities as the government rethinks the balance between economic growth and environmental protection.

Officials and experts in Beijing debated at the weekend a plan to harness the Nu River in southwest Yunnan province with a chain of up to 13 hydro-power stations amid signs of revived official favor for the project.

The whole project, which could take a decade or more to build, would generate more power than the mammoth Three Gorges Dam, and displace 50,000 farmers, say supporters.
