Ministry spokesman Noh Kyu-duk told a regular briefing that the government is doing its best while remaining prudent in order to achieve results in the upcoming inter-Korean summit regarding various issues including denuclearization.
The spokesman said the foreign ministry was doing its necessary part in tandem with government posture.
