The southeast Asian nation had less than a fortnight to prepare for the two world leaders – far less than the two months Singapore took to plan for last year’s summit.
However, the Vietnamese Government quickly swung into action to provide “maximum security” for the two world leaders.
After Air Force One touched down, Mr Trump tweeted effusively about Vietnam and suggested it could be a model for North Korea to follow.
“Vietnam is thriving like few places on earth,” he wrote.
“North Korea would be the same, and very quickly, if it would denuclearize. The potential is AWESOME, a great opportunity, like almost none other in history, for my friend Kim Jong Un. We will know fairly soon -Very Interesting!"
The meeting between President Trump and Mr Kim was sealed with a handshake and laughs, came ahead of a meal with discussions expected to build on last year's breakthrough meeting in Singapore.
Ahead of the meeting, Mr Trump expressed his hopes that North Korea could develop a strong economy in exchange for denuclearisation.
The US delegation want North Korea to completely dismantle their nuclear arsenal in a verifiable way. Whilst a priority for North Korea will be a request for the US to end the sanctions that have crippled their economy in recent years.
At last year’s summit between the two leaders, Pyongyang committed itself to the “complete denuclearization of the Korean Peninsula”.
Critics, however, panned the Singapore Declaration as high on "pageantry" but lacking in mechanisms to enforce it.
Mr Trump has since tweeted that he expected, “a continuation of the progress made at first Summit in Singapore”, before adding: “Denuclearization?”
There is, however, speculation at the summit that a formal end to the Korean War could be declared.
