U.N. Secretary-General Ban Ki-moon said Tuesday he will visit the Kaesong industrial complex just north of the inter-Korean border, which will make him the first U.N. chief to enter the isolated country in more than two decades.

The Kaesong industrial complex, a special economic zone a few kilometers north of the heavily fortified border, is jointly run by North and South Korea.

"All parties would benefit from renewed engagement and commitment to genuine dialogue. It is essential for building trust and promoting inter-Korean relations," Ban said at an education forum in the South Korean city of Incheon, adding he aimed to make the visit Thursday.
