Exports grew 11.4 percent on-year, reaching $57.9 billion last month, while imports rose by 6 percent to $54 billion. This resulted in a trade surplus of $3.83 billion, marking the country's 15th straight month in the black since June of last year.
The semiconductor sector led the surge, with chip exports soaring 38.8 percent from a year earlier to $11.9 billion, extending their growth for the 10th month in a row and setting a new record for August.
The shipbuilding industry also saw significant gains, with exports jumping 80 percent on-year to $2.8 billion. Exports of petroleum products also edged up 1.4 percent to $4.5 billion.
However, the automotive sector faced setbacks. Exports of automobiles fell by 4.3 percent to $5.1 billion, due to production disruptions amid wage negotiations.
In terms of export destinations, shipments to China — the country's largest trading partner — rose 7.9 percent to $11.4 billion, fueled by strong demand for semiconductors and mobile devices. Exports to the U.S. also saw an impressive uptick, increasing 11.1 percent to $10 billion, the highest figure recorded for August.
"With the highest growth rate among major global exporters, Korea is on track for record-breaking figures," Minister Ahn Duk-geun said in a statement.
