South Korea's chief delegate Lee Su-hyuck explained his country's position and tried to gain a better understanding of the North's position during the closed-door session, sources told the Korea Times.
Delegates from China, Japan, North Korea, Russia, South Korea and the United States will begin talks around a hexagonal-shaped table Wednesday in Beijing.
In the talks, scheduled to end Friday, South Korea, Japan and the United States seek the ultimate dismantling of the North Korea nuclear program, including the one allegedly based on highly enriched uranium.
In addition to the talks, two-way meetings between Pyongyang and Washington are also expected on the sidelines.
