The government hopes total investment commitments to Indonesia will surge by 50 percent after a new policy designed to open up several business sectors to foreign players is issued, according to a top official. The new policy will be made by revising the negative investment list (DNI). Investment Coordinating Board (BKPM) head Franky Sibarani said the opening of more business sectors would help boost investment commitments to the country by 50 percent this year.
