Connection and modernization of railways in the Korean peninsula's eastern transportation corridor is a declared step within the historic April 27, 2018 joint declaration for peace, prosperity, and unification.

Activity around Wonsan is likely to be a leading indication of inter-Korean joint declaration progress given its role both in the eastern transportation corridor and the national economy.
