Donald Trump And Kim Jong-Un Meet In Vietnam For Second Summit

US President Donald Trump and North Korean leader Kim Jong-un have greeted each other with handshakes and smiles as they met again in Hanoi, Vietnam..

Held in the Vietnamese city of Hanoi, the meeting is intended to bring about North Korea's denuclearisation, and possibly provide a formal end to the Korean War.

The two men previously met last June in Singapore. That historic summit ended with some backslapping and fine words, but little solid progress has been made since.

If a deal is reached, it would give Trump a rare foreign-policy victory at a time when his presidency is increasingly embattled at home.
