A barbershop in Hanoi is offering customers free Donald Trump and Kim Jong Un hairstyles ahead of the pair’s summit in the Vietnamese capital next week.

At the shop tucked away in a small alley, Le Phuc Hai, 66, patiently waits for his hair dye to bleach his natural black into the colour of the president of the United States.

On a chair next to him, nine-year-old To Gia Huy emerges as a spitting image of a miniature Kim Jong Un.

“Many people say that I look like Kim Jong Un, especially when I have this hairstyle,” said Huy, who was nicknamed “Un” for his likeness to the North Korean leader.

He was unable to hide his excitement that Mr Kim is coming to the city next week for his second summit with the US president, and hopes for a chance to see him in person.

As the summit frenzy shakes Hanoi, hairdresser Le Tuan Duong has joined in, offering free Trump or Kim hairstyles to about a dozen customers.

“Hanoi is a city of peace. When Donald Trump and Kim Jong Un decide to come here to talk about restoring peace, I think I should do something to show that Hanoi people welcome the summit,” Mr Duong said.

He said Mr Kim’s hairstyle shows youth while Mr Trump’s displays power.

“But Kim’s style is a lot more popular among customers,” he said.

Mr Hai, a motorcycle taxi driver, went for Mr Trump’s orange because he confessed: “I really like Donald Trump so I want to have (his) hairstyle.”
