The spokesman did not give further details.
Iraq earlier this month agreed a $5.4 billion standby loan with the International Monetary Fund. Finance Minister Hoshyar Zebari, announcing the agreement on May 19, said the IMF loans could unlock $15 billion more in international assistance over the next three years.
Iraq's economy has been hit by the plunge in oil prices since mid-2014 and the country is expected to have a financing gap of $17 billion this year unless it can secure more funding, an IMF document obtained by Reuters showed. The cost of fighting Islamic State militants is another burden on the budget.
