Northeast India is the eastern-most region of India. It comprises eight states – the contiguous Seven Sister States (Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura), and the Himalayan state of Sikkim. The Siliguri Corridor in West Bengal, with a width of 21 to 40 kilometres (13 to 25 mi),connects the North Eastern Region with East India, and separates Sikkim from the Seven Sister States. The region shares more than 4,500 kilometres (2,800 mi) of international border with China (Tibet Region) in the north, Myanmar in the east, Bangladesh in the southwest, and Bhutan to the northwest. The region comprises an area of 262,230 square kilometres, 8.0 percent of India.
