South Korea's exports for the first 20 days of September increased almost 23 percent on-year.
According to the Korea Customs Service, outbound shipments totaled more than 36 billion U.S. dollars.
Imports rose too, but there was still a trade surplus of a little over 1.1 billion dollars.
The rise was due to high demand for semiconductors, metals and cars.
With oil prices high, exports of petroleum products rose on year by 95 percent.
By destination, exports to the U.S. saw an increase of 25 percent and to China of just under 20 percent.
