South Korean short-term foreign debt decreased to the lowest figure since the Q4 of 2006 largely due to weaker Korean Won and curbed credit lean demand from exporters, a data unveiled by the Bank of Korea revealed on Wednesday. Short-term foreign debt dropped by $4.5 billion to a level of $122.2 billion in the first three months of 2013, while the long-term debt advanced by $1.3 billion to $288 billion in the Q1.
