India's foreign ministry said on Friday that New Delhi has conveyed its concerns to Beijing about China's plan to build a hydropower dam in Tibet on the Yarlung Zangbo river which flows into India.

China approved the construction of what will be the world’s biggest hydropower dam on the eastern rim of the ecologically fragile Tibetan plateau

Sources said India was not informed by the Chinese side about the construction of the Brahmaputra dam project, which is the convention between the two countries, and learnt of it from media reports – the project is to cost an estimated $137 billion.

Ministry of External Affairs spokesperson Randhir Jaiswal on Friday said that India has lodged protest with China through diplomatic channels over the establishment of two new counties in the Hotan Prefecture since parts of their jurisdiction fall in the Union Territory of Ladakh.
