After North Korean leader Kim Jong Un sat down with his Russian counterpart Vladimir Putin in Beijing, a team of North Korean staff carefully wiped down the items touched by the country’s leader.

Analysts say this was part of a set of security measures to prevent espionage.

Even as Kim and Putin showed signs of friendship, footage from the day before yesterday captured the exceptional measures taken by the isolated state to hide any evidence about Kim’s health.

Kremlin correspondent Alexander Yunashev posted a video on the Telegram app showing two staff members accompanying Kim meticulously cleaning the room in the Chinese capital where Kim and Putin met for more than two hours.

The two wiped the back of the chair and its armrests, cleaned the coffee table next to Kim’s seat, and removed the glass from which the North Korean leader drank.

The correspondent said, “After the discussions ended, the two staff members accompanying the Supreme Leader of the Democratic People’s Republic of Korea carefully removed all traces of Kim’s presence.”

After the talks in the hall, Kim and Putin left to have tea and warmly bid each other farewell.

As he did during previous foreign trips, Kim took his own toilet on board a distinctive green-colored train, transporting it to Beijing to hide health evidence, according to Japan’s Nikkei newspaper citing intelligence agencies in South Korea and Japan.
