South Korea's national debt, including that of public companies, reached 1,218 trillion won (US$1,135 billion) in 2012, or roughly 95 percent of the country's GDP, the country's largest federation of business groups said Tuesday. The findings released by Korea Economic Research Institute, the research arm of the Federation of Korean Industries (FKI), showed that the total debt size is 2.7 times larger than the government debt that stood at 443.1 trillion won for the one-year period.
