The regional security difficulty lies not only in Tibetan politics, but in the fact that the Yarlung-Tsangpo becomes the Brahmaputra once it crosses into India in Arunachal Pradesh, a territory disputed by India and China and heavily militarized. Diversions affecting the Brahmaputra would imperil India's own water security, including hydropower and irrigation projects, and would have further impacts downstream in Bangladesh. Although China may see its water projects as increasing its own security, India and Bangladesh view the Chinese actions as a direct threat to their national security. Specifically, China's actions have the potential to increase the risk of water-related population stresses, cross-border tension, and migration and agricultural failures for perhaps a billion people in India and Bangladesh, and its actions may be interpreted as a security threat by India
