"There exist many ecological and environmental problems concerning the Three Gorges Dam," the senior officials were quoted as saying. "If no preventive measures are taken, the project could lead to catastrophe."

Tensions over residents resettled to steep hills where good farmland is scarce had been reduced and water quality in the dam was "generally stable", Xinhua said. But the officials and experts were worried about the landslides threatening densely populated hill country.
