Indonesia's economy grew 5.78 per cent in 2013, the slowest pace in 4 years, dpa quoted the Central Bureau of Statistics as saying Wednesday. Gross domestic product rose 5.72 per cent in the fourth quarter compared to the same period last year, the bureau said. Last year's growth was mainly driven by exports and domestic consumption, it said. South-East Asia's biggest economy has posted growth of more than 6 per cent since 2010, as a growing middle class consumes more.
