Emerging markets are expected to help South Korea maintain its export momentum in the second half amid slowdowns in advanced economies, a report said Thursday. The Korea Trade-Investment Promotion Agency (KOTRA) report predicted that shipments to Europe and the United States may decline in the second half as these countries struggle to deal with financial and fiscal uncertainties. Consumer spending gains stood at just 0.4 percent in the United States, while numbers in Britain, France and Japan fell into minus territory, it said.
