However, yesterday he also tweeted: “Great week of humanitarian work in Guam and Tokyo, Japan now just got to Beijing..Guess what’s next? #Peace #Love #NotWar”

Moreover, attached to the tweet was a picture of Rodman wearing a shirt with the word “unite” written underneath images of him, Donald Trump and Kim Jong-un.

The ex-athlete has traveled to North Korea at least five times this year and has served as a gateway to the international community and Pyongyang.

News of a sixth visit to North Korea has prompted speculation over whether Mr Rodman will try to improve diplomatic relations between Pyongyang and Washington, especially as he is a mutual friend of both Donald Trump and Kim Jong-un.

He also tweeted his support for the Republican’s presidential campaign in 2015.

Earlier this year, Mr Rodman, in an interview on Good Morning Britain told host Piers Morgan: “For me to go over there and see [Kim] as much as I have, I basically hang out with him all the time.

“We laugh, we sing karaoke, we do a lot of cool things together.

In the interview, he also said he would like to “straighten things out” between enemy nations North Korea and the US.

News of Rodman potentially meeting with Kim Jong-un has come after the dictator hinted at boosting North Korea’s nuclear arsenal in his latest threat to trigger World War 3.

He made the comments to top North Korean military officials after reportedly climbing the hermit state’s tallest mountain.

Pyongyang’s state media released an image of the despot at the top of Mount Paektu, which is considered a sacred site in Korea.

The United States and South Korea conducted large-scale military drills last week to counter the threat posed by Pyongyang.

The North reacted with fury, saying the drills had made the outbreak of war “an established fact”.
