HONG KONG — Among the many questions about a meeting between President Trump and Kim Jong-un, the North Korean leader, is where it might happen.

Mr. Trump is known for being a reluctant traveler. Mr. Kim is even more of a homebody, not leaving North Korea since he took over after his father’s death in 2011.

But if the two do meet, which some White House officials believe will never happen, they will need a venue suitable for such a historic moment. Here are a few options:

The Demilitarized Zone

The village of Panmunjom in the Demilitarized Zone between the two Koreas might be the most promising location. Occasional meetings have been held in a small conference room that straddles the dividing line in the Joint Security Area and that has entrances on either side of the border.

The Peace House on the South Korean side of Panmunjom is a larger building perhaps more suitable to a meeting between the two leaders. North and South Korean representatives met there to plan the North’s participation in the Winter Olympics last month in the South. And Mr. Kim has said he would go there to meet South Korea’s president, Moon Jae-in.
