Countries proceeded with project after UN Security Council granted exemptions to sanctions
A South Korean train entered to North Korea on Friday as the two countries began inspecting northern railways tracks they hope to relink with the south.
About 30 officials from each side will participate in an 18-day joint survey of railways tracks cut since the Korean War.
“We will maintain close consultation with related nations so that the project to connect the South and North’s railways could proceed with international support,” South Korean Unification Minister Cho Myoung-gyon said during a ceremony at Dorasan Station near the border.
