A South Korean official says that the rival Koreas' top nuclear envoys could meet during an unofficial security forum in the United States this week.
Both envoys are scheduled to attend the three-day forum in New York starting Wednesday. It follows a breakthrough disarment-for-aid deal between Pyongyang and Washington last week.
A meeting between the Koreas is important because the United States has said that Pyongyang improving ties with Seoul is crucial to any diplomatic resolution of the nuclear standoff.
Foreign Ministry spokesman Cho Byung-jae said Monday that no meeting between the envoys has yet been arranged at the forum but they could still meet.
North Korea has ramped up rhetoric threatening Seoul in recent days.
