Iranian President Hassan Rouhani will inaugurate the first phase of the port of Chabahar, known as Shahid Beheshti port, on Sunday.
The port will open a new strategic transit route to Afghanistan and Central Asia for India through Iran, without going through Pakistan.
It is believed that Iran asked the Indian government to “administer” or operate the first phase of the port, until the work for the second phase ends.
In addition to the bilateral agreement to develop the port of Chabahar, for which India will invest $ 500 million, India, Afghanistan and Iran have also signed a trilateral Agreement on Transport and Transit Corridor.
Delegates from 27 countries, including India and Afghanistan, will attend the inauguration of the port.
The port, located on the coast of the Gulf of Oman, in the province of Sistan-Baluchestan, southeast of Iran, has two docks.
More than a month ago, India sent the first shipment of wheat to Afghanistan through the port of Chabahar, which Swaraj commented as a gift from the Indians to Afghans.
Swaraj said afterwards that India remains committed to working closely with its regional and international partners to bring peace, security, stability and prosperity to Afghanistan.
In boosting bilateral relations between India and Iran, Foreign Minister Sushma Swaraj also made an unannounced visit to Tehran on her way back from Sochi, Russia, before the opening of the strategically important port.
Iran has invested approximately one billion dollars in the construction of the first phase of the port.
The Director General of Ports and Maritime Organization of the Iranian province of Sistan and Baluchistan, Behrouz Aqaee, said that around 100,000 tons of ships will be able to call the port once it becomes operational.
