A new government report says that China's Three Gorges Dam project has doubled in cost.

It will now require $25bn more than the initial cost of $25bn to resettle people displaced by the project and to fill the reservoir with enough water.

A lack of rain and other problems are delaying the opening of the dam - designed to be the world's biggest flood-control and hydropower facility.

Al Jazeera's Melissa Chan reports.
