India has reduced imports of oil from Iran from 12% in 2011 to about 9% by the end of April, 2012. A senior state department official from the U.S., Carlos Pascual, will be in India in mid May 2012 to assess the energy situation and see what specific energy facilities in India need to do. Some of the refineries in India are designed to handle only the kind of heavy oil Iran supplies. For the U.S. the issue is keeping up the pressure on Iran during the talks in Istanbul, Turkey, on Iran's nuclear program. For India it has the vital trade and economic relationship with the U.S. balanced against cultural ties to the region and the need for oil supplies.
