On the other hand, Pakistan issued a demarche to India saying it was becoming hard for its diplomats to function in Delhi.
"We offered to participate in the China-Pakistan Economic Corridor". Iran's offer may also be seen as a move to placate Pakistan's deep misgivings over India's long-standing involvement in the Chabahar Port project.
The development comes in the backdrop of India and Iran inking an agreement to lease operation control of a part of the port to New Delhi for 18 months.
Frequent ceasefire violations have been reported on the Line of Control and Working Boundary by India; in fact the highest number of breaches took place a year ago since the 2003 ceasefire accord took effect leaving 87 people dead. He also said that the Chabahar port project was not meant to "encircle Pakistan ... strangulate anybody", adding that Iran would not allow anybody to hurt Pakistan from its territory, much like Pakistan would not allow its soil to be used against Iran.
Pakistan's Army Chief General Qamar Javed Bajwa has told the visiting Iranian Foreign Minister Mohammad Javad Zarif that "wider cooperation in West Asia is needed" to tackle security challenges threatening the region.
Zarif likened Irans relations with India to Pakistans ties with Saudi Arabia. During his meeting with Janjua on Tuesday, Zarif talked about "tapping into the potential of Gwadar and Chabahar ports" to boost economic cooperation, according to a statement from Iran's foreign ministry.
He also repeated Iran's commitment that it would not allow India to carry out any activities against Pakistan. Zarif said, "There is no reason for hostility between Iran and Saudi Arabia".
"We are taking measures to do that and there is an open invitation to Pakistan to participate in that", Zarif said.
Chabahar is said to be becoming a success story in the India-Iran relationship.
Singh was summoned after Pakistani newspaper Dawn quoted Pakistani officials of accusing India of harassing its diplomats and their families in the country and threatened to pull out the families if the intimidation did not stop.
In this context, India's not likely to be pleased with the Iranian foreign minister's comments.
