Tehran announced during the weekend that it would invite 60 countries to attend what Iranian officials describe as a two-day disarmament summit scheduled to start April 17.
The Indian ambassador to Tehran is expected to attend the summit in Tehran, the Calcutta Telegraph reports.
New Delhi in 2006 voted against Iran in a nuclear measure before the International Atomic Energy Agency and again in November 2009. The 2006 vote was seen as a tacit support for political change in Iran during a low point in U.S.-Iranian relations.
The Tehran visit would follow a similar conference scheduled next week in Washington, where Indian Prime Minister Manmohan Singh is expected to attend.
India officials, meanwhile, are wary over U.S.-supported plans to incorporate moderate elements of the Taliban into the political fray in Afghanistan.
New Delhi said recently it was scaling back its mission in Afghanistan temporarily following heightened security concerns.
India, also to the detriment of Washington, said it would take another look at plans to build a natural gas pipeline through Iran and Pakistan.
Washington opposes the project, dubbed the Peace Pipeline, because of the economic incentives for Iran.
