The Chabahar port in Iran will be a top priority for Prime Minister Narendra Modi, who is set to visit the country on 22-23 May.
During his visit, India, Afghanistan and Iran are expected to sign a pact to develop the Chabahar port and establish a transit-transport corridor, which will also enable India to access markets in Central Asia.
The agreement will be signed at the ministerial level in the presence of PM Modi, Iranian president Hassan Rouhani and Afghan president Ashraf Ghani on 23 May.
The visit is also expected to see progress on India's proposal to allow ONGC Videsh Ltd (OVL) to develop the Farzad B gas field in Iran.
PM Modi's visit will not just revolve around concluding connectivity projects and energy deals. he will also visit Iran's only Gurdwara - which has been operational since the 1940s.
The visit will allow the two countries to "expand bilateral cooperation and mutually benefit from new opportunities in the wake of lifting of secondary sanctions against Iran earlier this year," the Ministry of External Affairs said.
