Bijan Namdar Zanganeh is quoted by the semiofficial Mehr news agency today as saying that Iraq's oil policies are to Iran's detriment.
Iran's oil exports are believed to have fallen from about 2.5 million to over 1.2 million barrels a day as a result of a Western oil embargo against Iran over Tehran's uranium enrichment programme.
The US and its allies fear that Iran may ultimately be able to develop a nuclear weapon, a charge Iran denies. Iran generally enjoys good relations with Iraq's Shiite-led government.
