China-backed dam in Indonesia rainforest to cut through home of world’s rarest orangutan
● Dam site is the only known habitat of orangutan species that numbers about 800
● Sinohydro, which built Three Gorges Dam, awarded design and construction contract

A billion-dollar hydroelectric dam development in Indonesia that threatens the habitat of the world’s rarest great ape has sparked fresh concerns about the impact of China’s globe-spanning infrastructure drive.
The site of the dam in the Batang Toru rainforest on Sumatra island is the only known habitat of the Tapanuli orangutan, a newly discovered species that numbers about 800 individuals in total.
The US$1.6 billion project, which is expected to be operational by 2022, will cut through the heart of the critically endangered animal’s habitat, which is also home to agile gibbons, siamangs and Sumatran tigers.
Indonesian firm PT North Sumatra Hydro Energy is building the power plant with backing from Sinosure, a Chinese state-owned enterprise (SOE) that insures overseas investment projects, and the Bank of China, company documents show.

Chinese SOE Sinohydro, which built the mammoth Three Gorges Dam, has been awarded the design and construction contract for the project.
