Renho, the new state minister in charge of government revitalization, reiterated Wednesday her intention to trim waste in special account budgets, saying some aspects of the spending technique call for a thorough investigation by her team.

"This is a big theme," the high-profile Renho, who at 42 is the youngest member of the Cabinet, said during her inaugural news conference.

Special account budgets are used for specific government projects using revenue closely related to that project. For example, the government uses the gasoline and coal tax to develop new oil and gas fields under a special energy policy account.
