Sistan and Baluchestan province (Persian: استان سيستان و بلوچستان) is the second largest of the 31 Provinces of Iran, after Kerman province, with an area of 180,726 km. Its capital is the city of Zahedan. The province is in the southeast of the country, bordering Afghanistan and Pakistan.
The name of the region was simply Baluchistan at first, but later became "Baluchistan and Sistan" before becoming "Sistan and Baluchestan".
The Gwadar Port (Urdu: گوادر بندرگاہ [ˈɡwaːdəɾ ˈbəndəɾɡaː]) is situated on the Arabian Sea at Gwadar in Balochistan province of Pakistan and is under the administrative control of the Maritime Secretary of Pakistan and operational control of the China Overseas Port Holding Company. The port features prominently in the China–Pakistan Economic Corridor (CPEC) and is considered to be a link between the Belt and Road Initiative and the Maritime Silk Road projects. It is about 120 kilometres (75 mi) southwest of Turbat, and 170 kilometres (110 mi) to the east of Chabahar Port (Sistan and Balochistan Province in Iran).
The potential of Gwadar to serve as a deep-water port was first identified in 1954, when the city was still under Omani rule. Plans for construction of the port were not realised until 2007, when the port was inaugurated by Pervez Musharraf after four years of construction, at a cost of $248 million.
