Kim Jong-un, North Korea’s leader, is expected to arrive in Vietnam next Monday ahead of a planned second summit on nuclear disarmament with Donald Trump, the US president.
Mr Trump and Kim are due to meet in the Vietnamese capital, Hanoi on Wednesday and Thursday, aiming to break an ongoing deadlock since they first met in Singapore last June over the denuclearisation of the Korean peninsula.
However, three sources told Reuters that Kim will travel in advance to the communist-ruled nation for bilateral meetings with Vietnamese officials.
If confirmed, it would be the first state visit of a North Korean leader since his grandfather, Kim Il-sung, travelled to the country in 1964.
Kim could also visit Vietnam’s manufacturing base of Bac Ninh, east of the capital, and the industrial port town of Hai Phong.
A Reuters witness saw Kim’s close aide, Kim Chang Son, in Hanoi on Saturday visiting a government guesthouse and the Metropole and Melia hotels in the city centre.
