The official Xinhua News Agency on Sunday quoted Pu Haiqing, head of the Cabinet-level Three Gorges Project Construction Committee, as saying that total would be reached before the project is completed in 2008.
The number of people already relocated has reached 1.2 million people, surpassing the original estimate of 1.13 million, Pu said.
According to the report, Pu said the higher number of dislocated people resulted from consideration for the local ecology. It did not give additional details.
The $22 billion dam on the Yangtze River was completed this spring. Its power generation facilities are slated to be finished by 2008.
