S Korea's exports record biggest drop since 2009

South Korea's exports, the main driver of the national economy, suffered their sharpest drop in more than six years in January, extending what is now a 13-month losing streak.

Government data released Monday showed exports down 18.5 percent from the same month last year at $36.7 billion -- the steepest decline since August 2009.

The report cited a host of factors, such as slowdowns in major economies, including South Korea's biggest trade partner China which accounts for a quarter of the country's exports.

Falling global oil prices also contributed to the dismal figure, hitting petroleum products that are a mainstay export item for Asia's fourth largest economy.
