The Asian Development Outlook supplement updates the economic forecasts of the Asian Development Outlook 2012 Update for the regional economies of developing Asia. According to this Supplement's findings, the surging economies of Southeast Asia have been a bright spot in an otherwise subdued 2012 growth performance in developing Asia, but the broader region should still pick up steam in 2013. Mixed third quarter data broadly support the forecasts in October’s Asian Development Outlook 2012 Update for developing Asia, with downside developments slightly outweighing positive events.
