Hwanghae-do has been an economically and culturally developed region from early days. Handicrafts such as Goryeo porcelain enabled Gaeseong, capital of the Goryeo Dynasty (918-1392) to develop thriving external trade and serve as a commercial center in both the Goryeo and Joseon eras. Currently, South-North economic cooperation has been actively progressing here through the joint operation of the Gaeseong Industrial Complex.
