US President Donald Trump landed in Hanoi on Tuesday for two days of talks to try to persuade North Korean leader Kim Jong-un to give up his nuclear arsenal.

Trump arrived on Air Force One after flying half way around the world from Washington, while Kim arrived earlier, following a two-and-a-half-day train journey from Pyongyang. They were due to have dinner Wednesday and continue talks on Thursday.

The normally chaotic streets of central Hanoi ground to a halt as Kim’s convoy arrived in the Vietnamese capital.

Curious onlookers gathered next to televisions crews outside the luxurious Melia hotel in Hanoi’s diplomatic district, waiting for hours under chilly, gloomy skies for a glimpse of the North Korean leader as he drove from the border city of Dong Dang after crossing China by train.

His black Mercedes Benz, in the middle of a convoy of at least a dozen cars, flanked by multiple police outriders, arrived shortly after 11am local time to crowds lining the streets, waving North Korean, US and Vietnamese flags, and holding up smartphones to record the moment.
