Assam (Assamese: অসম Ôxôm) is a north eastern state of India with its capital at Dispur, a suburb of the city Guwahati. Located south of the eastern Himalayas, Assam comprises the Brahmaputra and the Barak river valleys and the Karbi Anglong and the North Cachar Hills. With an area of Assam currently is almost equivalent to the size of Ireland or Austria. Assam is surrounded by the rest of the Seven Sister States: Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura and Meghalaya. These states are connected to the rest of India via a narrow strip in  West Bengal called the "Chicken's Neck". Assam also shares international borders with Bhutan and Bangladesh; and cultures, peoples and climate with South-East Asia—important elements in India's Look East Policy. Assam is known for Assam tea, petroleum resources, Assam silk and for its rich biodiversity. It has successfully conserved the one-horned Indian rhinoceros from near extinction in Kaziranga, the tiger in Manas and provides one of the last wild habitats for the Asian elephant. It is increasingly becoming a popular destination for wild-life tourism and notably Kaziranga and Manas are both World Heritage Sites. Assam was also known for its Sal tree forests and forest products, much depleted now. A land of high rainfall, Assam is endowed with lush greenery and the mighty river Brahmaputra, whose tributaries and oxbow lakes provide the region with a unique hydro-geomorphic and aesthetic environment.
