China announced plans to build three dams - Dagu, Jiacha and Jiexu - on the river last month as part of its aggressive plan to provide energy and water needs for its 1.3 billion people.
The Chinese government said that the hydropower dams would not impact flood control efforts or the ecological environment in downstream regions.
Experts said that if the projects were carried out, they would have devastating consequences on the lives of millions of people in India and Bangladesh.
Agriculture forms the backbone of the economy in both Assam and Arunachal Pradesh with nearly 80 percent of the 27 million people in the two states eking out a living through farming, an agriculture scientist said.
India and China do not have a water-sharing agreement. However, both countries have instituted a working group mechanism to exchange data, including measurement of water flow from rivers.
