A top US official has said that India should make its own decisions on the relationship with Iran based on its interests. At the same time, the countries should take a hard look at their business partners in Iran. <br/><br/>The senior Trump administration official was responding to a question about India developing the strategically located Chabahar port in Iran, which will give it access to Afghanistan and then to Central Asia.<br/><br/>An agreement on the Chabahar port was inked by India and Iran in May 2016 after detailed discussions between Prime<br/>Minister Narendra Modi and Iranian President Hassan Rouhani. <br/><br/>As per the pact, India is to equip and operate two berths in Chabahar Port Phase-I with capital investment of 85.21 million US Dollar and annual revenue expenditure of 22.95 million US Dollar on a 10-year lease. <br/><br/>Earlier this month, the US slapped sanctions on the IRGC (Iran's Islamic Revolutionary Guard Corps-controlled companies) for its alleged support to various terrorist organisations. <br/><br/>The official said that countries doing business with Iran also need to ensure that their economic relationships with Iran do not lead to the strengthening of the IRGC in particular and their ability to do so much harm to so many people, the official added.<br/><br/>The senior administration official said, Talks between India and the US in this regard if any are happening through normal channels all the time.<br/>
