Balochistan (/bəˈloʊtʃɪstɑːn, bəˌloʊtʃɪˈstɑːn, -stæn/ bə-LOHTCH-ist-a(h)n, -A(H)N; Balochi: بلۏچستان, romanized: Balòcestàn, [baˈloːt͡ʃest̪ɑːn]), also spelled as Baluchistan or Baluchestan, is a historical region in West and South Asia, located in the Iranian plateau's far southeast and bordering the Indian Plate and the Arabian Sea coastline. This arid region of desert and mountains is primarily populated by ethnic Baloch people.Balochistan is very significant because of its strategic location, mineral wealth, long coastline at the mouth of the Persian Gulf, and potential for discoveries of oil and gas.
The Balochistan region is split among three countries: Iran, Afghanistan and Pakistan. Administratively it comprises the Pakistani province of Balochistan; the Iranian province of Sistan and Baluchestan, along with southern Kerman province, southern South Khorasan province and eastern Hormozgan province; and the southern areas of Afghanistan, which include Nimruz, Helmand and Kandahar provinces. It borders what was historically the Pashtunistan region to the north, Sindh and Punjab to the east, and Persian regions to the west. Its southern coastline, including the Makran Coast, is washed by the Arabian Sea, in particular by its western part, the Gulf of Oman.
