1. The north eastern region of India is surrounded by foreign countries, about 98 percent of the boundary having been bordered internationally. Thus the region appears almost detached from the mainland of the country, at the same time having no mutual contact with neighbouring countries. Inside the region, the states are separated from one another by hill tracks resulting in the own-styled growth of the states in respect of food habits, races and languages, economy, employment, culture etc. So the people of these states generally bear identities specific to the concerned states.
