South Korea's current account surplus rises

South Korea's current account surplus rose in September to $6.57 billion, keeping its surplus trend for 20 straight months, central bank data showed Tuesday.

Current account surplus was $6.57 billion in September after recording a $5.68 billion surplus in the previous month, according to the Bank of Korea, Xinhua reported.

Exports account for around half of the economy and increased 2.5 percent from a year earlier to $420.64 billion in September after falling 2.7 percent in the previous month.

Imports reduced 1.9 percent year-on-year basis to $378.81 billion last month, pushing the September trade surplus to $41.84 billion.

The figures came amid deepening concerns over the South Korean currency's appreciation against the dollar. The won and dollar exchange rate continued to fall after touching this year's high of 1,161 won June 24.
