"BEIJING: China has begun building a 314-metre (1,030-ft) high dam which will be among the world's tallest, officials said, as the country massively expands hydropower.

The Shuangjiankou dam on a tributary of China's mighty Yangtze river will be completed in 2022, the environmental ministry said on its website Tuesday.

The facility, costing 36 billion yuan ($5.8 billion), will be higher than the world's current tallest dam, the 305-metre Jinping-1, also in China.

China has been expanding its hydropower electricity generating capacity as it seeks to reach a goal of obtaining 20 per cent of its power from non-fossil sources by 2030."
