North Korean leader Kim Jong-un, who arrived in Singapore Sunday for the landmark meeting, took a surprise nighttime tour of Singapore’s iconic sites, Monday.

Liang Tuang Nah, a research fellow at the Institute of Defense and Strategic Studies in Singapore, does not think the outing has any deeper implications.

“It’s more diplomatic courtesy and being a gracious guest in Singapore than anything else,” he said.

“Certainly Kim would like wealth and development for North Korea but one must remember that his father also saw the sights when he visited China, observing a stock exchange and visiting a GM vehicle factory.”
