China said on Wednesday that the construction of the Yarlung Zangbo hydropower project falls within its sovereignty and will not have adverse effects on downstream areas.

Foreign Ministry spokesman Guo Jiakun made the remarks after it was reported that India and Bangladesh expressed concerns, fearing damage to biodiversity and livelihoods of local people.

"The project aims to accelerate the development of clean energy, greatly improve local livelihoods, and actively address climate change," Guo told a daily news briefing.

"China has always maintained a highly responsible attitude toward transboundary river development and has rich experience in hydropower project development," Guo said.

He added that the planning, design, and construction of the project strictly adhere to China's highest standards in the sector, avoiding and relocating from several important and sensitive ecological areas to preserve the original ecosystem to the greatest extent.

Guo further noted that the construction of the project is beneficial for disaster prevention and mitigation throughout the entire river basin and will not have adverse effects on downstream areas.

"China has conducted hydrological reporting, flood control, and disaster reduction cooperation with relevant downstream countries and has also engaged in necessary communication regarding the project," he said, adding that the nation will continue to strengthen cooperation with downstream countries.
