Ban would be the first UN chief to visit the factory park, which opened in 2004 in the town of Kaesong. He would also be the first head of the UN to visit North Korea since Boutros Boutros-Ghali traveled there in 1993.
Ban's trip comes as relations between the Koreas remain strained following the North's continuation of missile and other weapons tests that South Korea views as provocation.
Ban told reporters today during his trip to South Korea that he would spare no efforts in trying to help improve ties between the Koreas.
"The Kaesong project is a win-win model for both Koreas.

It symbolizes a good aim to tap the advantage of South and North Korea in a complementary manner," said Ban, who visited the factory park in 2006, when he was South Korea's foreign minister. "I hope my visit will provide positive impetus to further develop it and expand to other areas."
But analyst Chang Yong Seok at Seoul National University's Institute for Peace and Unification Studies said he was skeptical about whether Ban's trip can bring any major breakthrough in ties between the rivals.
Chang said North Korea accepted Ban's Kaesong complex visit because it could be helpful in its push to lure foreign investment and revive its troubled economy. But, he said, "North Korea won't welcome Ban coming to Pyongyang with talks on its nuclear program."
It has survived periods of animosity, including the North's artillery bombardment of a South Korean island in 2010, while other cross-border projects, such as tours to a scenic North Korean mountain, remain deadlocked.
