Its location lies in the Gulf of Oman. It is the only Iranian port with direct access to ocean.Doval, who attended the 51st Munich Security Conference last week, said Asia will have an important role in international developments in future and Iran along with countries such as China and India should play their roles in economic and political fields.He said Chabahar can become the North-South Corridor in the region and India looks to it as a place for quick development of relations.Secretary of Iran's Supreme National Security Council (SNSC) Ali Shamkhani said Iran and India play significant role in establishing peace in the region.In his meeting with Doval, Shamkhani said Iran and India are two neighbors without joint borders and the two sides' political leaders are determined to broaden cooperation in line with their national interests and maintaining stability of the entire region.
