An interesting moment was caught on camera shortly after the North Korean leader met with Vladimir Putin, on the eve of celebrations in Beijing to mark the anniversary of Japan's surrender in World War II.
The meeting ended with both leaders looking satisfied.
A short time later, North Korean staff entered the room and carefully cleaned all the furniture that Kim Jong-un had touched and removed his glass.

A video posted on Telegram shows a worker cleaning Kim's place, taking care to clean both the wooden arms of the chair and the table next to her. At the same time, another worker removed her glass, which was on a tray.
