Organizers of a women’s international peace walk across the Korean Peninsula’s heavily mined Demilitarized Zone next month said Friday that the governments of both North and South Korea had given their conditional approval for the event, which is meant to create new pressure for a formal end to the Korean War. But the organizers acknowledged that they did not yet have the final written confirmations or visa approvals.

Participants in the walk, which includes a number of Nobel laureates and disarmament activists, are planning to go regardless and have purchased plane tickets, the organizers said. North Korea, the starting point for the May 24 walk, also has presented the organizers with a tentative itinerary.

“At this point we consider having obtained the approval of both governments,” said Suzy Kim, a professor of Korean history at Rutgers University who is one of the organizers of the event, which was first announced last month. “It just takes some paperwork to proceed.”

The organizers, who also include Gloria Steinem, the feminist author and an honorary co-chairwoman, held a news conference in New York to provide an update on their progress in arranging the walk, which was conceived to punctuate their desire for a permanent peace treaty to replace the armistice that halted — but technically never ended — the 1950-1953 Korean War.
