South Korea's exports jumped nearly 30 percent from a year earlier in February to mark the highest level ever recorded for the month, driven by strong demand for semiconductors, government data showed Sunday. Outbound shipments totaled $67.45 billion last month, up 29 percent from $54.2 billion a year earlier, according to the data compiled by the Ministry of Trade, Industry and Resources. Imports rose 7.5 percent on-year to $51.94 billion, resulting in a trade surplus of $15.51 billion, the data showed.
