Chinese authorities have begun constructing what will be the world's largest hydropower dam in Tibetan territory, in a project that has sparked concerns from India and Bangladesh. Chinese Premier Li Qiang presided over a ceremony marking the start of construction on the Yarlung Tsangpo river on Saturday, according to local media.

Satellite imagery gives a glimpse of the site where China has commenced construction on what will become the world's largest dam and China's most ambitious infrastructure project since the Three Gorges Dam. Newsweek reached out to the Chinese Foreign Ministry and Power Construction Corporation of China via email for comment outside of office hours.

The project on a river that runs through Tibet and India downstream could dwarf the Three Gorges Dam when completed.
