NEW DELHI - Iran has turned to India for wheat supplies as other sellers divert grain cargoes away from the Middle East country because of sanctions-related payments problems that have caused palm oil imports to grind to a halt.Indian tea was also added on Thursday to a growing list of Iran's food imports that are being disrupted by US and European Union sanctions aimed at forcing Tehran to scrap a suspected nuclear weapons program.India's Trade Secretary Rahul Khullar said a private Iranian buyer is interested in importing "a very large quantity" of wheat, which the world's second-biggest producer of the crop has in surplus.Khullar, the most senior official in the ministry, suggested India was considering the sale. India wants to step up exports to Iran in a range of goods to settle part of its oil due to Tehran.
