Oman's ministry of national economy has said that government revenues during the first half of 2010 rose by 30.5% to OR4.22bn compared to OR3.23bn during the corresponding period in 2009, Oman Daily Observer has reported. The increase was mainly due to a 54% increase in oil revenues and a 21.7% rise of gas revenues during the period. The government's total general expenditure rose by 8.8% during the first six months of 2010 to OR3.52bn, against OR3.23bn during the same period of the previous year.
