SINGAPORE — For a couple of world leaders looking to get away to work on their relationship, Singapore has some obvious advantages.

On the law and order front, bullhorns, banners, drones and spray paint have all been banned around the resort island where President Trump and Kim Jong-un, the leader of North Korea, are expected to hold their historic summit meeting on Tuesday. And street demonstrations of any sort, even solitary ones, require a police permit that would be hard to come by given the circumstances.

Singapore’s strict security was a selling point in deciding the summit meeting’s location, and it has already come into play. The Singaporean police announced on Friday that two South Korean journalists who were trespassing in the North Korean ambassador’s residence had been arrested. And a Kim Jong-un impersonator from Hong Kong posted on social media that he was questioned for a few hours upon arriving in Singapore.

The country’s history as a trading center and neutral diplomatic player also makes it one of the few places in the world with relatively cordial ties to both North Korea and the United States.
