SEOUL — Prime Minister Lee Nak-yon pledged Monday to share with the world South Korea’s experience in restoring forests devastated by the 1950-53 Korean War, saying it would help cope with climate change and other environmental challenges. Speaking at a gathering of forestry ministers from the Asia-Pacific area, Lee also called for the region to work together to prevent illegal logging through a multilateral cooperation mechanism. “Despite the hopeless situation (following the 1950-53 Korean War), South Korea succeeded in forest restoration within less than 20 years, and in the process, South Korea received much assistance from the international community,” he said at the Meeting of Ministers Responsible for Forestry of the Asia Pacific Economic Cooperation (APEC) forum.
