The Foreign Ministry plans to oblige officials dispatched to diplomatic missions abroad to submit receipts when claiming management expenses at overseas government establishments in the fiscal 2002 budget, ministry officials said.

Management expenses for diplomatic missions are usually classified as "special operational funds," the remainder of which need not be returned. They can also be carried over to subsequent fiscal years.

But the special operational funds are being criticized as too similar to discretionary funds, which do not require receipts as proof for reimbursement, the officials said.
