China completed construction on Saturday of the controversial Three Gorges Dam, the world’s largest hydroelectricity project, and marked the occasion with a subdued ceremony broadcast live on state television.
A brass band played and confetti rained over the site after workers poured the last batch of concrete.
No top officials attended the event, in contrast to the launch of work on the dam in 1997, for which then-President Jiang Zemin and then-Premier Li Peng were both present.
