He recalled his experience in traveling to the North himself and "expressed hope that (South Korea) will cooperate with the international community on the resumption of humanitarian assistance" for the country in parallel with making headway in its denuclearization, the ministry said.

He told Kang he could enhance understanding of the reality of a divided Korea through his tour a day earlier of the Demilitarized Zone bisecting the peninsula.

"So it was a little bit like that yesterday, making a relatively short journey of Panmunjom and then seeing the reality being introduced by the military there, both Korean and American, and to understand the very delicate situation that exists there, which makes the efforts to promote denuclearization, unification and peace on the peninsula very, very pertinent indeed," he said at the outset of the talks with Kang.

He also said it is the responsibility of all the Catholic believers to "mobilize every possible (opportunity) to make peace" on the Korean Peninsula.

The ministers also exchanged views on various global issues, including refugee crises and Syria.
