The trip is part of efforts to implement an agreement reached in October to jointly combat pine tree pests and other forestry diseases until March next year, the ministry said.

South Korea sent about 50 tons of pesticides to the North late last month to help it combat the spread of pine tree diseases.

The South Koreans will review the distribution of the chemicals and visit a local tree nursery and other facilities to discuss with their North Korean counterparts ways to expand their cooperation, the ministry said.

In August, the Koreas conducted a joint field survey of the area near Mount Kumgang on the North's east coast to examine the damage caused by diseases to trees.

They also agreed during talks in October to push for the modernization of 10 tree nursery plants in North Korea this year, while promising to work together in combating forest fires and protecting ecosystems. (Yonhap)
