Here are few things learned so far

Sister act

Kim’s younger sister Yo Jong, whom he sent to the South’s Winter Olympics as his special envoy, has emerged as one of his closest advisers and is regularly seen at his side at public events. But she is developing a tendency to stray into shot.

Field of view

All major South Korean television channels carried wall-towall coverage of Moon’s arrival in Pyongyang.

But the North’s media is tightly controlled and often eschews live broadcasts, preferring to show recorded footage.

Disputed islands

The unification flags waved by North Koreans at the airport showed a map of the peninsula, clearly including Dokdo, ■ ■ ■ islands controlled by Seoul but claimed by Tokyo.

When similar flags were used ahead of the Winter Olympics in the South, Japan swiftly protested, and Seoul rapidly came up with an alternative version without the blue specks. But Pyongyang is strongly nationalistic and constantly denounces Japan’s 20th-century colonisation of the peninsula and its wartime atrocities.

Bait and switch

Kim and Moon got into separate vehicles at Pyongyang airport before driving away. But by the time the convoy arrived at the Paekhwawon State Guesthouse where Moon and his closest advisers are staying, they were in the same open-topped car.
