<P> The waters of the River Brahmaputra are shared by China, India, and Bangladesh . In the 1990s and 2000s, there was repeated speculation that mentioned Chinese plans to build a dam at the Great Bend, with a view to divert the waters to the north of the country . This has been denied by the Chinese government for many years . At the Kathmandu Workshop of Strategic Foresight Group in August 2009 on Water Security in the Himalayan Region, which brought together in a rare development leading hydrologists from the basin countries, the Chinese scientists argued that it was not feasible for China to undertake such a diversion . However, on 22 April 2010, China confirmed that it was indeed building the Zangmu Dam on the Brahmaputra in Tibet, but assured India that the project would not have any significant effect on the downstream flow to India . This claim has also been reiterated by the Government of India, in an attempt to assuage domestic criticism of Chinese dam construction on the river, but is one that remains hotly debated . Recent years have seen an intensification of grassroots opposition, especially in the state of Assam, against Chinese upstream dam building, as well as growing criticism of the Indian government for its perceived failure to respond appropriately to Chinese hydropower plans . </P> <P> In a meeting of scientists at Dhaka at 2010, 25 leading experts from the basin countries issued a Dhaka Declaration on Water Security calling for exchange of information in low - flow periods, and other means of collaboration . Even though the 1997 UN Watercourses Convention does not prevent any of the basin countries from building a dam upstream, customary law offers some relief to the lower riparian countries . There is also potential for China, India, and Bangladesh to cooperate on transboundary water navigation . </P> <P> The lives of many millions of Indian and Bangladeshi citizens are reliant on the Brahmaputra river . Its delta is home to 130 million people and 600 000 people live on the riverine islands . These people rely on the annual' normal' flood to bring moisture and fresh sediments to the floodplain soils, hence providing the necessities for agricultural and marine farming . In fact, two of the three seasonal rice varieties (aus and aman) cannot survive without the floodwater . Furthermore, the fish caught both on the floodplain during flood season and from the many floodplain ponds are the main source of protein for many rural populations . </P> <Ul> <Li> Current <Ul> <Li> Bogibeel Bridge </Li> <Li> Dr. Bhupen Hazarika Setu </Li> <Li> Kolia Bhomora Setu </Li> <Li> Naranarayan Setu </Li> <Li> Saraighat </Li> </Ul> </Li> <Li> Planned (under - construction, approved, proposed, etc .): Nitin Gadkari announced following 5 new bridges in Dec 2017 . <Ul> <Li> Jorhat - Nematighat </Li> <Li> Disangmukh - Tekeliphuta </Li> <Li> Louit - Khablu </Li> <Li> Numaligarh - Gohpur </Li> <Li> North Guwahati - Guwahati </Li> </Ul> </Li> </Ul>
