North Korean leader Kim Jong Un arrived in Vietnam on Tuesday for a summit with U.S. President Donald Trump where they will try to reach an agreement on a North's Korean pledge to give up its nuclear weapons program.

Trump is due to arrive in the Vietnamese capital, Hanoi, on Tuesday evening.

Trump will meet Kim for a brief one-on-one conversation on Wednesday evening, followed by a social dinner, at which they will each be accompanied by two guests and interpreters, White House spokeswoman Sarah Sanders told reporters on Air Force One.

She said that would be followed by more meetings between the two leaders on Thursday.

Their talks come eight months after their historic summit in Singapore, the first between a sitting U.S. president and a North Korean leader.

While there is no real expectation that the second meeting will bring a final deal on ridding North Korea of nuclear weapons that threaten the United States, there are some hopes it could lead to a declaration that the 1950-53 Korean War is at last formally over.
