Howard X, the lookalike of Kim, arrived at Vietnam’s capital of Hanoi on Friday along with his partner who impersonates Trump, drawing crowds and media.
The two world leaders are due to meet for their second nuclear summit in Hanoi on Wednesday and Thursday.
“North Koreans have no sense of humour,” the impersonator told reporters before heading to Hanoi’s airport to leave the country.
The impersonator visited Singapore in June, when Trump and Kim held their first summit, and performed satirical stunts. He said he was briefly detained by authorities there.
“Please no World War Three,” Howard X said,”they are scared of a couple of guys that look like real thing.”
He also showed up at the 2018 Winter Olympics in South Korea, where he danced in front of an appalled North Korean cheer squad before security hauled him away.
