"It is true that different currencies will have an impact on the Korea's export capabilities and competitiveness. We have seen quantitative easing with Japan resulting in a lower yen and that of course is a factor that is influencing our competitiveness in the world market," Choi said.
"However, Korea is of the position that foreign exchange rates should be determined by the market and we let the market decide how the rates should be," he added.
Another round of stimulus?
Discussing the health of the broader economy, Choi said there is some evidence of a recovery, however he is not ruling out further stimulus in the second half of the year if needed.
Last July, the government unleashed a $40 billion stimulus package to revive the country's flagging economy.
"The Korean economy is growing at about mid-3 percent and compared to many of the OECD countries, this is actually rather a solid figure, however, I believe there's much room for further growth," he said.
"In order for that to occur, we are not only looking at the export market but also the domestic market," he said.
