South Korea's economy expanded in the first quarter at its fastest pace in two years, but the central bank report failed to brighten the prospects for the rest of the year as both consumers and exporters struggle for confidence.

The data showed on Thursday the economy grew a seasonally adjusted 0.9 percent from a weak fourth quarter of 2012. But compared with a year earlier, it grew just 1.5 percent, a pace unchanged from the fourth quarter, which was a three-year low.
