South Korea could revise downward its growth outlook for this year, the nation's top economic policymaker hinted Monday, citing lingering uncertainties at home and abroad. "Overall, there are downside risks (on growth)," Finance Minister Bahk Jae-wan told a forum held in central Seoul. "We stick to our growth outlook at this moment but I think we should make an accurate forecast again later." His remarks come after the government revised down its growth projection for this year from 5 percent to 4.5 percent in June. The revision was announced along with its economic management plan for the second half of this year, which puts more focus on taming inflation.
