The Brahmaputra River is one of the major trans-boundary rivers in Asia that cuts through four countries: China, India, Bhutan and Bangladesh. Therefore, it is known by different names in different regions. The origin of this river is in the Angsi Glacier, which is located on the northern side of Himalayas in Burang County, Tibet. Local people call it Yarlung Tsangpo River. It flows across southern Tibet, breaks through the Himalayas in great gorges and into Arunachal Pradesh (India).
