SEOUL, Sept. 11 (Xinhua) -- South Korea's top diplomat said Monday that the Korean Peninsula nuclear issue would be the biggest challenge to her country for years to come.
The peninsula nuclear issue "remains the biggest challenge on our foreign affairs and security front and will continue to be so for many years to come," Foreign Minister Kang Kyung-wha told a press conference with foreign correspondents in Seoul.
