"Gadkari will be visiting Iran. During his visit India and Iran may sign a memorandum of understanding for development of Chabahar port," an official source said.
Significantly, last US Under Secretary of State for Political Affairs Wendy Sherman has said India and other countries should "not rush" into doing business with Iran as Washington is yet to work out its nuclear deal with Tehran.
Chabahar port is located in Sistan-Baluchistan Province on Iran's south-eastern coast and is of great strategic utility for India, which will get sea-land access route into Afghanistan bypassing Pakistan.
Last week, Prime Minister Narendra Modi had assured Afghan President Ashraf Ghani of India's commitment to building the port.
Earlier, Gadkari had also said, "We are setting up a port in Chabahar, Iran... We will complete the port in about one- and-a-half years... The distance between Chabahar to Gujarat is less than Delhi to Mumbai."
The port will be used to ship crude oil and urea, saving the country in transportation cost.
